Front

If each of the flasks shown has the same volume and temperature, which flask contains the most gas particles?

Back

Flask 4 contains the most gas particles.

Front

In a rigid metal tank containing oxygen gas, what happens when additional oxygen is added at constant temperature?

Back

The average speed of the gas molecules remains the same.

Front

What happens to a balloon's volume when placed in the freezer?

Back

The balloon's volume will decrease.

Front

What is an assumption of the kinetic-molecular theory of gases?

Back

The temperature of a gas depends on its kinetic energy.

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

Back

The pressure of the gas increases.

Front

What is the ideal gas law equation?

Back

PV = nRT, where P is pressure, V is volume, n is number of moles, R is the ideal gas constant, and T is temperature.

Front

What is the effect of increasing temperature on the volume of a gas at constant pressure?

Back

The volume of the gas increases (Charles's Law).

Front

What is the effect of decreasing the number of gas particles in a container at constant volume and temperature?

Back

The pressure of the gas decreases.
