Heat moved from the hot water to the frozen object until the substances reached the same temperature.

Heat moved from the frozen object to the hot water until the substances reached the same temperature.

Heat moved in both directions between the objects.

Heat did not move between both objects.

The heat is transferred from the liquid to the ice.

The cup and lid will prevent the ice from melting.

The liquid will freeze if enough ice cubes are added.

The ice will stay frozen for at least 8 hours.

Heat moves from object A to object B.

Heat moves from object B to object A

The soft drink cans will absorb cold energy from the stream’s water.

The cans will lose heat until their temperatures are the same as the stream’s.

The temperature of the soft drinks will not change since the cans are sealed

The temperature of the cans will decrease to freezing as long as the stream is flowing.
