# What happens when gas is compressed into a smaller space?

## What happens when gas is compressed into a smaller space?

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.

## When a gas is compressed into a smaller space the pressure increases?

Explain why pressure increases as a gas is compressed into a smaller volume? Pressure increases because there will be more gas molecules per unit volume. The number of collisions with the given unit of wall area in the container per unit time will increase as a result.

What is it called when you squeeze gas into a smaller space?

COMPRESS. To squeeze a gas into a smaller space.

What can be squeezed into a smaller volume?

Definitions – Fluids

Matter Anything that has mass, takes up space, and is made of particles.
Compressible Capable of being squeezed into a smaller volume.
Incompressible Not capable of being squeezed into a smaller volume.
Hydraulics The study of pressure in liquids.
Pneumatics The study of pressure in gases.

### Which will result in greater pressure?

Summary. An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.

### When does a gas occupy a smaller volume it exerts a higher pressure?

When a gas occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure (assuming the amount of gas and the temperature do not change). Since P and V are inversely proportional, a graph of 1/P vs. V is linear.

What happens when gas particles move faster in a container?

If they move faster, the particles will exert a greater force on the container each time they hit the walls, which leads to an increase in the pressure of the gas. If the walls of the container are flexible, it will expand until the pressure of the gas once more balances the pressure of the atmosphere.

What is to squeeze gas into a smaller space called?

WHen the gas gets exerted by the pressure the density increases because the gas is getting compressed into a smaller space. Ability to force a gas into smaller space is called what? It is called compressibility.

## Why does density increase when gas is compressed?

WHen the gas gets exerted by the pressure the density increases because the gas is getting compressed into a smaller space. WHen the gas gets exerted by the pressure the density increases because the gas is getting compressed into a smaller space.
