Does Venus have the dense atmosphere?
Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
Why does Venus atmosphere is hundred times more dense than the Earth atmosphere?
There is simply so much more 'stuff' in Venus' atmosphere. Earth's total atmosphere has a mass of around 5⋅1018kg, while the Venusian one has 5⋅1020kg, so this is 100 times more than what Earth has.
Why is the atmosphere of Venus so much hotter and thicker than that of Earth?
Venus is hotter due to the greenhouse effect: Venus has an atmosphere about ninety times thicker than that of Earth, and made almost entirely of carbon dioxide, which is one of the gasses that causes the greenhouse effect on Earth.
Which of the following is thought to explain why Venus has so much more atmospheric gas than Earth?
Venus has gained much more gas through outgassing than has Earth. Earth has lost much more gas to thermal escape than has Venus. Because of its lack of magnetic field, Venus has been able to gain gas through the impacts of solar wind particles, while Earth has not gained gas in this way.
How does Venus's atmosphere compared to Earth's atmosphere?
The atmosphere of Venus is 90 times more dense than that on Earth and it is made of 96.5% of CO2 and a 3% of nitrogen. This means that both planets have the same amount of Nitrogen on their atmospheres.
How did Venus develop such a thick atmosphere?
It is speculated that the atmosphere of Venus up to around 4 billion years ago was more like that of the Earth with liquid water on the surface. A runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of the levels of other greenhouse gases.
What is Venus's density?
5.24 g/cm³Venus / DensityThe atmosphere on Venus is much denser than on Earth and is made up mostly (96%) of carbon dioxide and the rest nitrogen. Venus's radius is 6 051 km and its mass is about 82% of Earth's mass. The mean (average) density of Venus is about 5.2 g/cm3.
How dense is Earth's atmosphere?
At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter), and the atmosphere is relatively dense. At 10,000 feet (3 km), the air pressure is 10 pounds per square inch (0.7 kg per square cm), which means molecules of gas that make up the atmosphere are less dense.
What is the upper limit for phosphine?
In a preprint made available in October 2020, a re-analysis of archived infrared spectral measurements in 2015 did not reveal any phosphine in Venusian atmosphere, placing an upper limit for phosphine concentration at 5 parts per billion by volume—a quarter of the spectroscopic value reported in September).
How much of Venus' atmosphere is in the troposphere?
The troposphere on Venus contains 99% of the atmosphere by mass. Ninety percent of the atmosphere of Venus is within 28 km of the surface; by comparison, 90% of the atmosphere of Earth is within 10 km of the surface. At a height of 50 km the atmospheric pressure is approximately equal to that at the surface of Earth.
How fast does the atmosphere rotate?
The upper layer of troposphere exhibits a phenomenon of super-rotation, in which the atmosphere circles the planet in just four Earth days, much faster than the planet's sidereal day of 243 days. The winds supporting super-rotation blow at a speed of 100 m/s (≈360 km/h or 220 mph) or more.
What is the meridional circulation on Venus?
Meridional (north-south) component of the atmospheric circulation in the atmosphere of Venus. Note that the meridional circulation is much lower than the zonal circulation, which transports heat between the day and night sides of the planet. All winds on Venus are ultimately driven by convection.
How much pressure is Venus?
The atmospheric pressure at the surface of Venus is about 92 times that of the Earth, similar to the pressure found 900 m (3,000 ft) below the surface of the ocean. The atmosphere has a mass of 4.8 × 10 20 kg, about 93 times the mass of the Earth's total atmosphere.
What is Venus's atmosphere like?
It is speculated that the atmosphere of Venus up to around 4 billion years ago was more like that of the Earth with liquid water on the surface.
What is the atmosphere of Venus?
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure found 900 m (3,000 ft) underwater on Earth.
If Tesla was on the path of making electricity be conducted through air, like WiFi, how come we can't do it now since technology advanced so much?
Edit: how about shorter distances, not radio-like? Let's say exactly like WiFi, in order for me to charge my phone even when I'm 5 meters away from the charger? Right now "wireless" charging is even more restraining than cable charging.
Ice burns make no sense to me on a molecular level. Your skin cells are damaged because they came in contact with molecules that move too slowly?
you can damage your skin via conduction on too hot and too cold objects (-5°C - 54 °C).
How effective is the JJ vaxx against hospitalization from the Delta variant?
I cannot find any reputable texts stating statistics about specifically the chances of Hospitalization & Death if you're inoculated with the JJ vaccine and you catch the Delta variant of Cov19.
Is there any form of matter that cannot be categorized on the periodic table?
ie: is there any mass that breaks the standard rules of how elements work?
Why is chickenpox more dangerous for adults?
Adults get more dangerous symptoms and are more likely to die because of chickenpox but why does it hit adults so much worse than children? Google couldn't tell the reason. It only told it is worse for adults but didn't tell why.
How much pressure is Venus?
The pressure on Venus is 1334 PSI or 92 times the pressure at sea level on Earth, which is 14.5 PSI. Now, in our oceans the pressure increases by 14.5 PSI every 33 feet. So, we're told that the atmospheric pressure on Venus is equal to the pressure on Earth at 3036 feet under the ocean?
Why is the pressure on Venus so high?
Why is the atmospheric pressure on Venus so high? The answer is that the mass of the atmosphere of Venus is very high compared to that of the Earth, by almost a factor of 100. On the other hand, the two planets have similar surface areas and similar gravitational accelerations at the surface.
Why can't a mass spectrometer detect S8?
The mass spectrometer not detect the S8 because the mass of the S8 molecule, 256.47 amu is beyond the range of the mass spectrometer instrument, 208 amu. Carbon Sulfide, CS, occupies the entire lower atmosphere of Venus along with S8.
What is Venus' atmosphere?
Venus has instead expelled a large amount of its crustal carbon into its atmosphere, mostly in the form of carbon dioxide. Atmospheric pressure (or water pressure, for that matter) is simply the weight of the atmosphere that one square inch (or any square unit) supports.
How much more stuff is in Venus' atmosphere?
There is simply so much more 'stuff' in Venus' atmosphere. Earth's total atmosphere has a mass of around 5 ⋅ 10 18 kg, while the Venusian one has 5 ⋅ 10 20 kg, so this is 100 times more than what Earth has.
How much atmosphere is there above sea level?
That simply means that there is 14.5 pounds of atmosphere above one square inch of surface at sea level on Earth. (To calculate the pressure at a given depth in the ocean, you only need to calculate the weight of the ocean above that depth.)
How much pressure is there in the atmosphere?
The atmospheric pressure on earth is, for the sake of argument, 14.5 PSI. That simply means that there is 14.5 pounds of atmosphere above one square inch of surface at sea level on Earth.
Overview
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of supercritical carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (1,350 psi), roughly the pressure found 900 m (3,000 ft) underwater on Earth. The Venusian atmosphere supports opaque clouds of sul…
History
Mikhail Lomonosov was the first person to hypothesize the existence of an atmosphere on Venus, based on his observation of the transit of Venus of 1761 in a small observatory near his house in Saint Petersburg, Russia.
Structure and composition
The atmosphere of Venus is composed of 96.5% carbon dioxide, 3.5% nitrogen, and traces of other gases, most notably sulfur dioxide. The amount of nitrogen in the atmosphere is relatively small compared to the amount of carbon dioxide, but because the atmosphere is so much thicker than that on Earth, its total nitrogen content is roughly four times higher than Earth's, even though on Eart…
Clouds
Venusian clouds are thick and are composed mainly (75–96%) of sulfuric acid droplets. These clouds obscure the surface of Venus from optical imaging, and reflect about 75% of the sunlight that falls on them. The geometric albedo, a common measure of reflectivity, is the highest of any planet in the Solar System. This high reflectivity potentially enables any probe exploring the cloud tops suf…
Possibility of life
Due to the harsh conditions on the surface, little of the planet has been explored; in addition to the fact that life as currently understood may not necessarily be the same in other parts of the universe, the extent of the tenacity of life on Earth itself has not yet been shown. Creatures known as extremophiles exist on Earth, preferring extreme habitats. Thermophiles and hyperthermophiles thrive at temperatures reaching above the boiling point of water, acidophiles thrive at a pH level o…
Evolution
Through studies of the present cloud structure and geology of the surface, combined with the fact that the luminosity of the Sun has increased by 25% since around 3.8 billion years ago, it is thought that the early environment of Venus was more like that of Earth with liquid water on the surface. At some point in the evolution of Venus, a runaway greenhouse effect occurred, leading to the current greenhouse-dominated atmosphere. The timing of this transition away from Earthlike is …
Observations and measurement from Earth
In 1761, Russian polymath Mikhail Lomonosov observed an arc of light surrounding the part of Venus off the Sun's disc at the beginning of the egress phase of the transit and concluded that Venus has an atmosphere. In 1940, Rupert Wildt calculated that the amount of CO2 in the Venusian atmosphere would raise surface temperature above the boiling point for water. This was co…
