Unit 9 Lesson 3 What Is Heat?
The Energy of Heat
Copyright © Houghton Mifflin Harcourt Publishing Company
• Heat is the energy that moves between objects of different temperatures.
• The difference in temperature makes the energy move.
• Heat moves from an object with a highertemperature to one with a lower temperature.

• Heat can move in different ways.
• Conduction is the transfer, or movement, of heat between two objects that are touching. It can also occur within an object.
Example :When you hold a snowball, heatfrom your hand is conductedto the snow.

• Radiation is the transfer of heat without matterto carry it.
• Heat from the sun radiates through space and the atmosphere before it warms Earth.
• Radiation of heat is done in all directions.
