• 388 K
• 288 K
• 258 K
• 0 K

Which of the following best describes the relationship between the volume and temperature of a gas as defined by Charles's Law?

• The volume and temperature of a gas are inversely related.
• The volume and temperature of a gas are directly related.
• The volume and temperature of a gas are exponentially related.

If the temperature of a gas is increased, what will happen to its volume (assuming all other properties are held constant)?

• The volume will decrease
• The volume will not change
• The volume will increase

If the volume of a gas is decreased, what will happen to the pressue of the gas (assuming all other properties are held constant)?

• The pressure will decrease.
• The pressure will increase.
• The pressure will remain the same.

Theoretically, all molecular motion would stop at what temperature?

• 0* C
• 0 K
• 273 K
• 273*C

Which of the following best supports why the pressure inside of a container of gas increasese if more gas particles are added?

• There are more particles hitting the wall and increasing the pressure.
• There are less particles in the center of the container.
• There is an increase of force of collisions between the particles.

According to Avagadro's Gas Law, which of the following is true?

• Equal volumes of different gases at the same temperature and pressure contain different amounts of gas (n).
• Equal volumes of different gases at the same temperature and pressure contain the same amounts of gas (n).
• Different volumes of different gases at the same temperature and pressure contain the same amounts of gas (n).
• Equal volumes of different gases at different temperatures and pressure contain the same amounts of gas (n).
