DE Chem - Gas pressure warm-up

Front

How is temperature related to the movement of particles?

Back

Temperature is directly related to the movement of particles; as temperature increases, the kinetic energy of the particles increases, causing them to move faster.

Front

Why can gases be compressed?

Back

Gases can be compressed because the particles are very far apart, allowing them to be pushed closer together.

Front

What best illustrates the particle arrangement in a gas?

Back

In a gas, particles are widely spaced and move freely, unlike solids where particles are closely packed.

Front

What happens to the pressure of gas in a heated container?

Back

The pressure of the gas inside a heated container will increase due to the increased kinetic energy of the particles.

Front

Which container will have a lower pressure?

Back

The container on the left will have a lower pressure if it has fewer gas particles or a larger volume compared to the right.

Front

Define gas pressure.

Back

Gas pressure is the force exerted by gas particles colliding with the walls of their container.

Front

What is the relationship between volume and pressure in a gas?

Back

According to Boyle's Law, the volume of a gas is inversely proportional to its pressure when temperature is held constant.

Front

Explain Charles's Law.

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature in Kelvin when pressure is constant.

Front

What is kinetic molecular theory?

Back

Kinetic molecular theory explains that gas particles are in constant motion and that this motion is related to temperature and pressure.

Front

How does increasing temperature affect gas volume?

Back

Increasing temperature causes gas volume to increase, as the particles move faster and spread apart.
