Butter is placed on a hot piece of toast and begins to melt. This is because--
the toast cools off quickly because of the cold butter
heat moves from a cold object to a hot object
heat is transferred from the hot toast to the butter
the transfer of heat will stop when the butter begins to melt
Friction causes an object to move slower (increase in time).
TRUE
FALSE
What object converts mechanical energy to sound energy?
guitar
candle
battery
flashlight
