1. Explain the difference between heat and temperature.

2. Describe the direction of thermal energy in objects of different temperatures.

3. What happens when thermal equillibrium is reached (all objects have the same temperature)?

During cooling, the kinetic energy of the molecules falls. why does this happen? a.the motion of the molecules increases. b. the motion of the molecules slows down. c.the van der waals forces between molecules decrease d. the forces of attraction between the molecules are overcome.
