## What will happen to the volume of gas when its pressure?

Boyle found that when the pressure of gas at a constant temperature is increased, the volume of the gas decreases. this relationship between pressure and volume is called Boyle’s law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.

## What happens to the volume and temperature of a liquid and gas when they are placed under pressure?

He found that if you pressurize a gas, its volume contracts. If you decrease its pressure, its volume increases.

## What happens to the volume and pressure of gas if its temperature increases?

The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. They strike the surface of the container with more force. If the container can expand, then the volume increases until the pressure returns to its original value.

## Why does the pressure increase when the volume decreases?

Decreasing the volume of a gas increases the pressure of the gas. 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.

## What do you expect to happen to the volume of gas if its pressure is reduced to half?

Explanation: You can use Boyle’s law, which states that pressure is inversely related to volume when other variables are held constant. If the final pressure of a gas is half of the initial, the volume must double if temperature is to remain the same.

## What is the relationship between volume and temperature of gas?

Charles’s law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant.

## Which equation gives the correct relationship between volume and temperature of a gas?

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.

## What happens to volume when temperature decreases?

These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general: The volume increases as the temperature increases, and decreases as the temperature decreases.

## What happens to gas when temperature increases?

The increase in temperature results in expansion of the gas because of the increased kinetic energy of the molecules in the gas, which is an increase in volume. If the same number of gas molecules occupy more volume, the density of the air decreases (the air becomes less dense). 3.

## Does volume of liquid change with pressure?

Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the liquid forms a solid.

## What happens when the pressure of a gas is decreased?

Decreasing Pressure The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle’s law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.

## What do you expect to happen to the volume of the gas?

If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. Gay Lussac’s Law – states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
