Read each question carefully and provide your best answer. Show all work for calculations.
1. Which of the following statements is NOT a postulate of the Kinetic Molecular Theory of Gases?
Gas particles are in constant, random motion.
The volume of individual gas particles is significant compared to the volume of the container.
Collisions between gas particles are elastic.
There are no attractive or repulsive forces between gas particles.
2. If the temperature of a gas is increased while keeping the volume constant, what happens to the pressure?
Pressure decreases.
Pressure increases.
Pressure remains constant.
Pressure first increases, then decreases.
3. According to Boyle's Law, at constant temperature, the pressure of a gas is proportional to its volume.
4. The ideal gas law is expressed by the equation PV = nRT, where R is the gas constant.
5. All real gases behave ideally under all conditions of temperature and pressure.
True
False
6. Charles's Law states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.
True
False
7. A gas occupies a volume of 2.5 L at 1.0 atm. If the pressure is increased to 3.0 atm while keeping the temperature constant, what is the new volume of the gas? (Show your work and state the law used).
8. Explain why increasing the temperature of a gas in a rigid container increases its pressure, in terms of the Kinetic Molecular Theory.
