If the air temperature drops to 30°F during the night, how has the kinetic energy
of the air particles changed?
Answer the following question in the space provided.
16 An ice cube sits in an open container of water placed outside on a sunny day.
The warmer water contacting the ice cube transfers energy to the ice cube
through what process?
Use the set-up shown in the diagram to give two examples of how adding energy
as heat to a system may result in a change of state.
Compare the speeds of particles in the ice, water, and air.
