Review Gases CP

Front

What does temperature represent in the context of gases?

Back

The average kinetic energy of the particles.

Front

What is the force exerted by a gas on the walls of its container called?

Back

Gas pressure.

Front

Which of the following is NOT an assumption of the kinetic theory of gases?

Back

Gases are always diatomic.

Front

What happens to the kinetic energy of a substance when it is heated from 50 ºC to 100 ºC?

Back

The kinetic energy has gone up but not doubled.

Front

What is absolute zero in Kelvin?

Back

The temperature at which all particles stop moving.

Front

Define gas pressure.

Back

The force exerted by gas particles colliding with the walls of a container.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

As temperature increases, the average kinetic energy of gas particles increases.

Front

What are the main components of the kinetic theory of gases?

Back

1. Gases consist of tiny particles. 2. Particles are in constant random motion. 3. Collisions between particles are elastic.

Front

What is the significance of elastic collisions in the kinetic theory of gases?

Back

In elastic collisions, total kinetic energy is conserved.

Front

What happens to gas pressure if the volume of the container decreases while the temperature remains constant?

Back

Gas pressure increases.
