Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. The Combined Gas Law combines Boyle's Law, Charles's Law, and Gay-Lussac's Law to relate the pressure, volume, and of a gas.
2. In the Combined Gas Law equation, temperature must always be expressed in .
3. If the pressure of a gas is held constant, the Combined Gas Law simplifies to Law.
1. Which of the following is the correct formula for the Combined Gas Law?
P1V1 = P2V2
V1/T1 = V2/T2
(P1V1)/T1 = (P2V2)/T2
P1/T1 = P2/T2
2. A gas occupies 10.0 L at 2.0 atm and 273 K. If the pressure is increased to 4.0 atm and the temperature to 300 K, what is the new volume?
5.5 L
11.0 L
4.0 L
1.8 L
1. A balloon contains 2.5 L of air at 101 kPa and 25°C. If the balloon is taken to a location where the pressure is 95 kPa and the temperature is -10°C, what will be the new volume of the balloon? Show your work.
2. Explain how the Combined Gas Law is derived from Boyle's Law, Charles's Law, and Gay-Lussac's Law. What assumption is made about the amount of gas?
1. If the temperature of a gas is doubled while keeping pressure constant, its volume will also double according to the Combined Gas Law.
True
False
2. The Combined Gas Law is only applicable to ideal gases.
True
False
