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

If you were going to use this pan to cook, what do you notice could be a problem?

• it is made of metal, a good conductor

• the handles are all metal and will be HOT

• the sides are all metal and will be HOT

• there is no food in the pan to cook
