Write a paragraph about heat energy.

Heat is energy. Heat energy can be transferred in three different ways. They are conduction, convection, and radiation. When food is in a oven that is called conduction. Conduction is heat transfer between two substances. That means that two things have to be touching to have heat. An example of radiation is when the sun's heat reaches the world and heats it. Two substances do not have to be touching. Radiation can be transmitted through space. Convection is heat transfer. Convection is caused by warmer areas moving into cooler areas and cooler areas move into warmer areas causing a current. Conduction, convection, and radiation are three ways to transfer heat.
