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

rise slowly
lower quickly
show very little change
rise quickly
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
Heat transfers from an area of ________ temperature to an area of _______ temperature.
high to low
low to high
high to high
low to low
Josh did an experiment recording the changes in temperature in sand and water when exposed to a light source, and then when the light source was removed. Josh noticed that the sand heated up faster than the water and then cools faster than the water. Josh concludes that
sand is the better insulator.
water is the better conductor.
water is the better insulator.
sand has a higher heat capacity.
Which statement best classifies how particles move during radiation?
The transfer of heat by particles with higher energy moving from one location to another.
The transfer of heat by particles as they come in contact with each other.
The transfer of heat through space WITHOUT particles of matter colliding or moving to transfer the energy.
The transfer of heat from an object of cooler temperature to an object of a higher temperature.
What is the type of heat transfer that occurs between particles as they collide within a substance or between two substances that are in contact?
conduction
convection
radiation
solar energy
Which particles have the most energy?
liquid
