Understanding Gas Pressure and Temperature

What happens to the pressure of a gas when its temperature is increased while keeping the volume constant?

• The pressure decreases.

• The pressure increases.

• The pressure stays the same.

• The pressure becomes zero.

According to Charles's Law, what happens to the volume of a gas when its temperature decreases at constant pressure?

• The volume increases.

• The volume decreases.

• The volume stays the same.

• The volume doubles.
