Read each question carefully and provide the best answer. Show all your work for calculation problems.
1. The Combined Gas Law states that the ratio of the product of pressure and volume to the absolute temperature of a gas is .
2. When applying the Combined Gas Law, temperature must always be expressed in .
3. If the volume of a gas is held constant, the Combined Gas Law simplifies to Law.
4. A gas occupies 10.0 L at 2.00 atm and 273 K. What is its new volume if the pressure changes to 1.00 atm and the temperature to 300 K?
5.49 L
21.97 L
10.98 L
18.25 L
5. Which of the following is NOT an assumption made when using the Combined Gas Law?
The gas is an ideal gas.
The number of moles of gas remains constant.
The gas particles have significant volume.
There are no intermolecular forces between gas particles.
6. A balloon contains 15.0 L of air at 99.0 kPa and 27.0 °C. If the pressure increases to 110 kPa and the temperature drops to 15.0 °C, what is the new volume of the balloon?
7. Explain how Boyle's Law, Charles's Law, and Gay-Lussac's Law are all incorporated into the Combined Gas Law.
8. The Combined Gas Law is only applicable to ideal gases.
True
False
9. Increasing the temperature of a gas while keeping pressure constant will decrease its volume according to the Combined Gas Law.
True
False
10. A gas sample has a volume of 3.0 L at 100 kPa and 25 °C. If the pressure is increased to 150 kPa and the volume is decreased to 2.0 L, what is the new temperature of the gas in Celsius?
