Temperature vs. HeatTemperature vs. Heat
Heat: The flow of energy due to a temperature difference
Heat transfer occurs from the hotter substance to the cooler substance

ConductionConduction• The transfer of energy as heat between particles
as they collide within a substance or between two objects in contact.
• EX: Soup warming on the stove; soup warms the bowl

ConvectionConvection• The transfer of energy by
the movement of fluids (gas or liquid) with different temperatures.
• EX: You crawl out of a smoky room because the hot smoky air rises and cool clean air sinks to the floor

RadiationRadiation• The transfer of energy by electromagnetic
waves• EX: infrared radiation, visible light, &
ultraviolet rays

Look at all of the paddle surfaces!
They allow for a lot of
FRICTION between water
molecules!

Friction between
molecules generates
heat energy!
We can measure the temperature
increase.
