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
