boiling water
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
Conductors are materials that...
Allow heat to pass through
Stop heat from passing through
