Unit 3.Review 3.4, 3.5, 3.6

Front

Average Kinetic Energy is another term for _____________.

Back

Temperature

Front

When there is an increase in temperature of a gas in an enclosed container, the pressure will also increase due to the: _____________.

Back

Increase in kinetic energy of molecules that results in more frequent collisions with the walls of the container.

Front

The more molar mass a gas has, the_________________ it moves.

Back

slower

Front

Which of the following statements is true concerning real gases? _____________.

Back

The observed pressure will be less than the ideal pressure and the volume for the real gas particles is more than the volume of the ideal gas particles.

Front

What happens to a real gas at low temperatures that makes it behave less ideally? _____________.

Back

Particles have less energy and so exert less pressure on the container.

Front

Define Kinetic Energy.

Back

The energy that an object possesses due to its motion.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of the particles in a substance also increases.

Front

Explain the concept of pressure in gases.

Back

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

Front

What is an ideal gas?

Back

An ideal gas is a theoretical gas that perfectly follows the gas laws at all conditions of temperature and pressure.

Front

What factors affect the behavior of real gases?

Back

Intermolecular forces, volume of gas particles, and temperature.
