1. Which of the following variables are combined in the Combined Gas Law?
Pressure and Volume
Pressure and Temperature
Volume and Temperature
Pressure, Volume, and Temperature
2. If the temperature of a gas is doubled and its pressure is halved, what happens to its volume?
It is halved
It remains the same
It is doubled
It is quadrupled
3. The Combined Gas Law states that the ratio of the product of pressure and volume to the absolute temperature of a gas is .
4. For the Combined Gas Law to be applicable, the amount of gas (number of moles) must remain .
5. A gas occupies 10.0 L at 2.00 atm and 273 K. If the pressure is increased to 3.00 atm and the temperature is increased to 300 K, what is the new volume of the gas? (Show your work and units)
6. The Combined Gas Law is derived from Boyle's Law, Charles's Law, and Gay-Lussac's Law.
True
False
7. When using the Combined Gas Law, temperature must always be expressed in degrees Celsius.
True
False
8. A balloon contains 15.0 L of air at 0.950 atm and 25°C. If the balloon is released and rises to an altitude where the pressure is 0.700 atm and the temperature is -15°C, what will be the new volume of the balloon? (Remember to convert temperature to Kelvin).
