If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 mL
• 204 mL
• 196 mL
• 160 mL

The pressure of a sample of dry air is held constant 2.25 atm while the temperature is decreased from 100. ^oC to 7.0 ^oC. The original volume of the sample is 43 L. Which of the following is closest to the final volume of the sample?

• 3.0 L
• 32 L
• 57 L
• 610 L

The volume of gas in a balloon is 1.90 L at  21.0 ^oC. The balloon is heated, causing it to expand to a volume of 5.70 L. What is the new temperature of the gas inside the balloon?

• 7.00 C
• 63.0 C
• 120. C
• 609. C

The volume of a sample of a gas at 273 ^oC is 200 liters. If the volume is decreased to 100 liters at constant pressure, what will be the new temperature of the gas?

• 0 K
• 546 K
• 273 K
• 100 K

A sample of oxygen gas in a closed system has a volume of 200 milliliters at 600 K. If the pressure is held constant and the temperature is lowered to 300 K, the new volume of the gas will be -

• 400 milliliters.
• 300 milliliters.
• 100 milliliters.
• 200 milliliters.

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit

• Kelvin
• It doesn't matter 

What about gases can be measured?

• Pressure and Volume
• Temperature, Volume, and Pressure
• Volume and Temperature
• Pressure, Temperature, Volume, and Moles
