Question: Why Does Volume Decrease When Pressure Increases?

What causes volume to increase?

When you heat a gas, both its vapor pressure and the volume it occupies increase.

The individual gas particles become more energetic and the temperature of the gas increases..

Why does volume increase when 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.

What happens when a piston is used to decrease the volume?

What happens when a piston is used to decrease the volume of a contained gas? a fewer gas particles exert a force on the piston.

What happens to pressure when temperature increases and volume stays the same?

Gay-Lussac’s Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up.

What happens to volume when pressure increases?

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.

Why is volume inversely proportional to pressure?

BRIAN M. Boyle’s Law is a relationship between pressure and volume. In this relationship, pressure and volume have an inverse relationship when temperature is held constant. … If there is an increase in the volume the molecules have more space to move, collisions happen less often and the pressure is decreased.
