Why does ice melt when placed in a room temperature container?
Heat is transferred from the ice into the container.
Heat moves from air and the container into the ice.
The ice loses the energy needed to hold it together as a solid.
Atoms of the water molecule come apart.

North
South
East
West

If Ms. Klepper goes camping and puts her cans of Coke, which are 75°F, in the river, which is 55°F, what will eventually happen to her Cokes?
Her cans of Coke will stay the same temperature (75°F).
Her cans of Coke will get warmer, because it's so hot outside.
He cans of Coke will freeze because the water is so cold.
Her cans of Coke will eventually become the same temperature as the water (55°F).

After holding an ice pack against his skin for 20 minutes, the man notices the ice pack is melting. Why is this happening?
radiation - the ice pack is now all melted
conduction - body heat transferred to the cold ice pack
convection - the water in the ice pack flowed in a circle pattern
conduction - heat came from the bigger object to the smaller
