101 325 pascals
It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high. One standard atmosphere which is also referred to as one atmosphere is equivalent to **101 325 pascals** or newtons of force per square metre (approximately 14.7 pounds per square inch).

## What will happen to the volume of a container if the gas is compressed?

During compression the volume (V) of a **gas decreases**. When this happens the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant reducing the temperature (T) also causes the gas to compress.

## What happens to the pressure inside of a container when the volume of a container of gas is reduced?

Because the volume has decreased the particles will collide more frequently with the walls of the container. Each time they collide with the walls they exert a force on them. More collisions mean more force so the pressure will increase. When the volume decreases the pressure **increases**.

## What happens to the pressure if the gas volume is cut in half while N and T are held constant?

## How much does air compress under pressure?

A gas will **compress proportionately to the amount of pressure exerted on it**. For example if you have a 1 cubic foot balloon and double the pressure on it it will be compressed to 1/2 cubic foot. Increase the pressure by 4 and the volume will drop to 1/4 the size etc.

## When you heat a gas What happens?
