If a door was left open between the bedroom (74 degrees) and the living room (68 degrees), what would likely happen to the temperatures after several hours?
nothing, they would not change
both rooms would become hotter

the bedroom temp. would lower and the living room temp. would rise
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
