Boyle’s Law can be used to calculate atmospheric pressure with a simple glass J-shaped tube. An experiment is done with two different diameter tubes in a laboratory. The smaller diameter tube resulted in a measured atmospheric pressure of 746 mmHg.
What is the significance of Boyle’s gas law?
Boyle’s law is significant because it explains how gases behave. It proves beyond a shadow of a doubt that gas pressure and volume are inversely proportional. When you apply pressure on a gas, the volume shrinks and the pressure rises. What is the formula for Boyle’s gas law?
Is it possible to prove Boyle’s law empirically?
Boyle’s law is a connection between pressure and volume. It asserts that under constant temperature, the pressure of a specific quantity of gas is inversely proportional to its volume. It is possible to prove the law empirically. The paper discusses a syringe-based experimental approach for verifying the law. What is Boyle’s law?
What is the relationship between pressure and length in Boyle's Law?
The graph between reciprocal of length and pressure is a straight line, which shows that pressure of the given mass of gas is inversely proportional to length of air column. It indicates the inverse proportionality of pressure and volume of a given mass of gas, hence verifies Boyle’s law.
Why is a quill tube used to verify Boyle’s law?
The quill tube is helpful in verifying Boyle’s law. Since the volume of gas inside the tube (V) = cross sectional area of the tube (a) × length of air column (l), Students learn about the properties of gases and their relationships. Students understand Boyles law and its applications.
What is the effect of atmospheric pressure on Boyle's law experiment?
In Boyle's experiment, the pressure of air increased when it was compressed into a smaller volume container. According to the kinetic theory, confining the gas particles in a smaller volume will increase the number of collisions and hence the total force of the collisions with the container walls.
What is the apparatus used in Boyle's law experiment?
Bourdon gauge is fitted with a transparent plastic back to allow students to see its working parts. The apparatus has nozzle for tube to use the hand pump and comes with a needle valve to control and release pressure. Supplied without oil and hand pump. This apparatus can be used with Water instead of Oil.
How do you calculate pressure in Boyle's law?
Let's say we change the volume of a gas under isothermal conditions, and we want to find the resulting pressure. Then, the equation of Boyle's law states that: p₂ = p₁ * V₁ / V₂ or p₂ / p₁ = V₁ / V₂ . As we can see, the ratio of the final and initial pressure is the inverse of the ratio for volumes.
How does Boyle's law apparatus work?
A scale is fitted behind the glass tube so the volume of the air space can be measured proportionately. The reservoir contains water based colored fluid and, when the reservoir is pressurised by a small air pump, the fluid is forced up the glass tube and can be seen to compress the air inside the tube.
What is the application of Boyle's Law?
You can observe a real-life application of Boyle's Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.
What are examples of Boyle's Law?
An example of Boyle's law in action can be seen in a balloon. Air is blown into the balloon; the pressure of that air pushes on the rubber, making the balloon expand. If one end of the balloon is squeezed, making the volume smaller, the pressure inside increased, making the un-squeezed part of the balloon expand out.
What is the standard pressure in Boyle's law?

What does Boyle's law state about pressure and volume?
This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.
How are pressure and volume related According to Boyle's law?
The Relationship between Pressure and Volume: Boyle's Law. As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart.
What is the conclusion of Boyle law experiment?
From these observations he concluded that for a constant temperature the product of the volume and pressure of an enclosed gas remains constant. This became Boyle's law, which is normally stated: The volume of an enclosed dry gas varies conversely with its pressure, provided the temperature remains constant.
How does Boyle's law apply to human breathing apparatus?
According to Boyle's law, if a given amount of gas has a constant temperature, increasing its volume decreases its pressure, and vice-versa. When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases.
What is Charles Law apparatus?
The Charles Law Apparatus allows us to verify the physics law that rules the volume variations of a gas (at constant pressure) as its temperature varies. Therefore we can measure the dilatation coefficient (at constant pressure). The burner, the tripod and the wire gauze are sold separately.

What are the steps to Boyle's Law?
Boyle's LawBoyle's Law states that when temperature is constant: P1V1=P2V2.Boyle's Law also states that pressure is inversely related to volume. This means that when pressure is increased, volume is decreased (and vice versa)Boyle's Law also states: P⋅V=k (k = the proportionality constant)
Why is it necessary to make Boyle's law vertical?
Why is it necessary to make the Boyle's law apparatus vertical ? Answer. If it is not vertical, the reading of mercury column will not be accurate.
Why does a glass tube fly upwards?
It has been known for the glass tube to fly upwards when the gas is at maximum pressure. To prevent this, check the compression joint holding the tube and any tube supports before use. (The apparatus is filled and emptied by removing the pressure gauge.)
Where is the volume of dry air found?
A sample of dry air is confined in a tall, wide glass tube by a piston of oil. The volume is found from the length of the air column, which should be clearly visible at the back of the class.
How to fill Bourdon gauge with oil?
To fill the apparatus with oil, unscrew the Bourdon gauge with a spanner and fill the chamber with a low vapour pressure oil. Tilt the apparatus in the final stage of filling in order to get enough oil into the main tube. When refixing the gauge, tighten the nut to get a good seal, but not so much that the thread is damaged.
What is the result of Boyle's law?
This is accompanied by an increase in the pressure exerted by the air on the balloon, as a consequence of Boyle’s law. As the balloon is squeezed further, the increasing pressure eventually pops it.
Why is Boyle's law important?
Boyle’s law is significant because it explains how gases behave. It proves beyond a shadow of a doubt that gas pressure and volume are inversely proportional. When you apply pressure on a gas, the volume shrinks and the pressure rises.
What is the empirical relation of pressure?
The empirical relation asserts that the pressure (p) of a given quantity of gas changes inversely with its volume (v) at constant temperature; i.e., pv = k, a constant, as proposed by physicist Robert Boyle in 1662.
How much pressure does a gas exert on the walls of a container?
A gas exerts a pressure of 3 kPa on the walls of container 1. When container 1 is emptied into a 10-liter container, the pressure exerted by the gas increases to 6 kPa. Find the volume of container 1. Assume that the temperature and quantity of the gas remain constant.
What is the law of gas?
Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it . In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant.
What is the product of the initial pressure and the initial volume of a gas?
In other words, the product of the initial pressure and the initial volume of a gas is equal to the product of its final pressure and final volume (at constant temperature and number of moles). ...
What is the law of balloons?
A balloon is a good example of Boyle’s law in action. The balloon is inflated by blowing air into it; the pressure of the air pulls on the rubber, causing the balloon to expand. When one end of the balloon is compressed, the pressure within rises, causing the un-squeezed section of the balloon to expand outward.
