What do gases do to fill space available to them?
What do gases do to fill whatever space is available to them? Gas particles spread out to fill a container evenly, unlike solids and liquids. When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container.
Do gases take up a lot of space?
Gases take up a lot of space because a. they have weak chemical bonds. b. they contains very few atoms. c. they have a small molar mass. d. their molecules have very little attraction for one another.
Does space have gas in it?
While hydrogen and helium make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist. … You will find large amounts of complex gases such as methane and ammonia on gas planets such as Jupiter and Saturn.
Is there air or gas in space?
There is no air in space because there is no gravity to condense the molecules of gases found there into air. On Earth, gravity holds nitrogen, oxygen and the other gases that compose the atmosphere together, but only to about 60 miles above the surface. A few particles of dust and molecules of gases float in space.
What is space gas called?
The gas between stars is mostly hydrogen and helium scattered at varying densities between the stars in our galaxy and other galaxies. The proportions of the gases are similar to those in the Sun. Interstellar gas supplies the raw material for star formation.
Are there gas molecules in space?
Atoms of noble gases like helium, neon and argon — odorless, colorless, single-atom gases with low chemical reactivity — have long been known to exist in outer space.
What does space smell like?
A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.
How cold is space?
Space is very, very cold. The baseline temperature of outer space is 2.7 kelvins (opens in new tab) — minus 454.81 degrees Fahrenheit, or minus 270.45 degrees Celsius — meaning it is barely above absolute zero, the point at which molecular motion stops.
What molecules are in space?
Observations with radio waves carried out in the seventies proved that interstellar space is not only full of hydrogen and dust, but also contains complex chemical compounds, or gaseous molecules, such as water (H20), ammonium (NH3) and methanol (CH3OH).
What happens to gas in space?
Gases (like air) expand to fill their containers, and in space there is no container, so it would simply expand until it is the same density as space itself.
How many gases are there in the universe?
If you look at the periodic table, there are only 11 elements that are gaseous. Of those 11, two of them make up the majority of the star: hydrogen and helium. This means the most common elements in the universe are hydrogen and helium.
Can gases occupy space?
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
What are the gases in space?
Types of gases in Space are hydrogen and helium that make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist.
How many molecules are there in space?
Aside from the obvious hydrogen (atomic and molecular) and helium, there are about 150 molecules, ranging from diatomics to 10-atom molecules that have been detected in interstellar and circumstellar space. List of interstellar and circumstellar molecules - Wikipedia
What are the elements that make up interstellar space?
While hydrogen and helium make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist. Scientists who study interstellar space use spectrometers to identify trace amounts of other molecules between the stars.
What are the elements in the universe?
When the universe began, researchers believe, it was made up of gas containing light elements—mostly hydrogen and helium. The first stars formed from this material, some 300 million years after the big bang. As these early stars burned their fuel, they fused the lighter atoms to produce heavier elements like carbon and oxygen, which astronomers refer to as metals. These heavier elements were spewed into interstellar space when the stars exploded as supernova. The birth and death of later generations of stars—made from gas polluted with these heavier elements—served to add even more heavy elements into the mix, making the overall chemistry of the universe increasingly metal-rich.
Why did Fumagalli use the Keck telescope?
Fumagalli and his colleagues used the Keck telescope to look at the faraway universe, dating back to a mere 2 billion years after the big bang. Because the universe was still young at the time and hadn't yet been so heavily polluted by metals, the researchers hoped to detect relatively pristine gas clouds. To figure out the chemical composition of the clouds, they studied the spectrum of light from a background quasar that had traveled through the gas on its way to the telescope.
Which element is the most abundant in the universe?
Hydrogen and helium are the most abundant gases in the universe as they are the simplest and lightest elements. Hydrogen is also believed to be the first element created after Big Bang.
How fast does air move?
If we assume sea level pressure (1 atmosphere) and room temperature (20 degrees Celsius) then the air molecules are moving at 464 meters per second (average) although the lighter ones ar going much faster.
Why is space the best place to find noble gas molecules?
In retrospect, space seems the perfect place to seek noble gas molecules, because these gases abound in the cosmos.
What are the impossible molecules that only appear in space?
In the gases of the Crab Nebula, astronomers discovered argonium in what was the first detection of a naturally occurring, noble gas molecule. Located in the constellation Taurus, the Crab Nebula (shown in a composite image from two telescopes) is the debris left over from a massive star ...
What was the first molecule in the universe?
Even after the discovery of interstellar argonium, astronomers continued their quest for the simplest noble gas molecule, helium hydride, the one that theorists had predicted decades ago.
Why are cosmic rays important?
Because cosmic rays lead to the creation of argonium, its abundance in interstellar space has also helped nail down the number of cosmic rays darting through the galaxy. “There are more cosmic rays than we thought before,” Gerin says. That’s important not only for future Captain Kirks wishing to minimize their exposure to the destructive radiation as they travel between star systems, but also to scientists studying the chemistry of the interstellar medium, because cosmic rays are the first step in the creation of other molecules as well.
Why do scientists know the wavelengths of argonium?
They thought they knew the wavelengths argonium produced, because scientists had created it in the lab decades earlier and measured its spectrum. But these laboratory molecules contained argon-40, which is by far the most common argon isotope — on Earth. But that’s only because the argon we breathe comes from the radioactive decay of potassium-40 in rocks.
What is the second most common element in the universe?
Helium is the second most common element in the universe, after hydrogen, and neon ranks fifth or sixth. And in interstellar space, where extreme temperatures and densities are the rule, noble gases do things they would never do on Earth. That includes forming molecules.
How much of the atmosphere is argon?
Argon is more than 20 times as common in Earth’s atmosphere as carbon dioxide but gets far less press. In fact, it is the third most abundant gas in the air you breathe. Nitrogen and oxygen make up 78 percent and 21 percent of Earth’s atmosphere, respectively, while argon accounts for most of the remaining 1 percent.

What gases are used in space?
This incredible controlled explosion is achieved by burning gases which are both light and extremely flammable. Liquid hydrogen and liquid oxygen are the signature fuels of the American space program.
What temperature does hydrogen gas vent?
When liquid hydrogen and the liquid oxygen are combined and combusted, the temperature in the main combustion chamber is 6,000 degrees Fahrenheit.
How does densification affect propellant performance?
Propellant densification can significantly improve this propellant’s properties relative to vehicle design and engine performance. Vehicle performance calculations based on an average of existing launch vehicles indicate that densified propellants may allow an increase in payload mass of up to five percent.
Why did SpaceX change the propellants in the Falcon 9?
The change, known as propellant densification, allowed engineers to cram more pro pellants into the Falcon 9 to further improve its lift capacity.
How does the ISS work?
When the supply ships arrive at the ISS they pump compressed gases into the pressurized tanks at the airlock nodes. This system then monitors and mixes nitrogen into the ISS atmosphere at the right concentrations to keep the astronauts safe.
How does water make oxygen?
So, they make their own oxygen through a process called electrolysis . Water is a molecule that is made up of two hydrogen atoms and one oxygen atom (H2O). Passing an electric current between two electrodes and through water will cause it to decompose into hydrogen gas and oxygen gas.
Why is liquid hydrogen cryogenic?
Because liquid oxygen and liquid hydrogen are both cryogenic—gases that can be liquefied only at extremely low temperatures —they pose enormous technical challenges. Liquid hydrogen must be stored at minus 423°F and handled with extreme care.
