1. Which of the following is a distinguishing property of gases?
- A. They have a fixed shape and fixed volume
- B. They have no fixed shape and no fixed volume
- C. They have a fixed shape but variable volume
- D. They have a fixed volume but no fixed shape
2. In terms of particle arrangement, what is the main difference between a solid and a liquid?
- A. Solid particles are arranged regularly in a fixed pattern; liquid particles are arranged randomly but still closely packed
- B. Solid particles move faster than liquid particles
- C. Liquid particles are arranged in a regular pattern; solid particles are arranged randomly
- D. There is no difference in particle arrangement between solids and liquids
3. Which statement correctly describes what happens during boiling in terms of kinetic particle theory?
- A. Particles gain enough kinetic energy to overcome intermolecular forces and escape from the liquid surface
- B. All particles in the liquid suddenly gain the same amount of energy
- C. The temperature of the liquid increases continuously throughout the process
- D. Particles lose kinetic energy as they change from liquid to gas
4. A fixed mass of gas is heated in a sealed container of constant volume. According to kinetic particle theory, what happens?
- A. The pressure increases because particles move faster and collide with container walls more frequently and forcefully
- B. The pressure decreases because particles spread out more
- C. The volume increases proportionally to the temperature increase
- D. The pressure remains constant because the container volume does not change
5. A heating curve for a pure substance shows a horizontal section when the substance is melting. Using kinetic particle theory, explain why the temperature remains constant during this phase change.
- A. The heat energy supplied is used to break down intermolecular forces rather than increase the kinetic energy and temperature of particles
- B. The substance has reached its maximum possible temperature
- C. All particles have stopped moving during the phase change
- D. The container is losing heat to the surroundings at the same rate it is being supplied
