Read each question carefully and provide your best answer. Show all your work for calculation problems.
1. Which of the following describes the relationship between pressure and volume of a gas at constant temperature?
Directly proportional
Inversely proportional
No relationship
Exponential
2. What happens to the volume of a gas when its temperature is increased at constant pressure?
Decreases
Increases
Stays the same
First increases, then decreases
3. Boyle's Law states that for a fixed amount of gas at constant temperature, the pressure and volume are proportional.
4. Charles's Law states that for a fixed amount of gas at constant pressure, the volume and absolute temperature are proportional.
5. The ideal gas law is expressed as PV = nRT, where R is the gas constant.
6. A gas occupies 12.5 L at 0.95 atm. If the pressure is increased to 1.5 atm, what is the new volume, assuming constant temperature?
7. A balloon has a volume of 2.5 L at 25 °C. If the temperature is increased to 50 °C, what is the new volume, assuming constant pressure? (Remember to convert temperatures to Kelvin)
8. According to Avogadro's Law, equal volumes of all gases at the same temperature and pressure contain the same number of molecules.
True
False
9. The Kelvin temperature scale is used in gas law calculations because it has a lower freezing point than Celsius.
True
False
10. Describe the main assumptions of the Kinetic Molecular Theory of Gases and explain how these assumptions relate to the ideal gas law.
