What happens to the volume of a gas if the pressure is decreased?

when the pressure of gas is decreased, the volume increases. 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 pressure of an ideal gas when its temperature is decreased?

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. If you heat a gas you give the molecules more energy so they move faster. Conversely if you cool the molecules down they will slow and the pressure will be decreased.

What happens when gas pressure decreases?

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.

How much should the volume of gas be increased if pressure of the gas is decreased to one tenth of its initial pressure at constant temperature?

At constant temperature, pressure is inversely proportional to volume: (PV = nRT, so P = nRT/V). The pressure ratio is the inverse of the volume ratio: Here, , so the increase in pressure is 11\%.

What happens to the pressure of a gas if you decrease its volume by one 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.

Why does the volume of a gas decrease when the temperature decreases?

Why does the volume of gas decrease as the temperature decrease? As temperature of gas molecules decrease, they become less energetic and move a lot slower and spread out a lot less. Thus, as temperature decrease, the volume of the gas decrease as well.

What happens to the gas when the temperature decreases?

If the volume of a container is decreased, the temperature decreases. This means that the volume of a gas is directly proportional to its temperature. 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.

How does pressure affect gas pressure?

The Effect of Pressure on a Gas The pressure and volume of a gas are inversely proportional. Therefore, as you increase the pressure on a gas, the volume decreases. This means that as the pressure on a gas increases, the gas has less space to spread out and the particles are closer together.

What affects gas 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.

What happens to the pressure of a gas when the number of moles decreases?

Suppose the amount is decreased. This means there are less gas molecules and this will decrease the number of impacts on the container walls. This means the gas pressure inside the container will decrease (for an instant), becoming lesser than the pressure on the outside of the walls.

How much should the pressure of the gas be increased to decrease the volume by 10\% at constant?

So, $11.1\\% $ of pressure should be increased in order to reduce the volume of gas by $10\\% $.

Should pressure be increased in order to decrease the volume of a gas by 5\% at a constant temperature?

We know that change in pressure is equal to the difference in the final pressure and the initial pressure. So, 5.26\% of pressure must be increased in order to decrease the volume of the gas by 5\%.

What happens when the pressure of an ideal gas decreases?

If the pressure of an ideal gas decreases by 10\% isothermally, then its volume will ___________. For a isothermal process, the temperature remains constant. So if pressure decreases so the volume will increase. Was this answer helpful?

What happens to volume when pressure decreases 10\% isothermally?

If the process is carried out isothermally, then T = constant. The as the gas goes from state 1 to state 2, we have – If pressure (p) decreased 10\% isothermally (T=const) then Volume (V) will increase 10\% simultaneously.

What happens to the volume of a gas when work is done?

When the gas does work the volume of a gas increases () and the work done is negative. When work is done on the gas, the volume of the gas decreases () and work is positive. One way to remember the sign convention is to always think about the change in energy from the point of view of the gas.

How do you decrease the pressure by 10\%?

So V²/V¹= 1.111 x P¹. Therefore to decrease the pressure by 10\% , you have to increase the volume by 1/9- times or by 11.11\% . According to Boyle’s law, for a gas of definite mass, at constant temperature, volume is inversely proportional to pressure.
