Hot Stuff The three forms of heat transfer. Heat Transfer What is Heat Transfer? How many types of heat transfer are there, and what are they?

Remember! Heat is transferred in three different ways:

Thermal Energy. 1.Thermal Energy is the vibration or movement of atoms and molecules. 2.All matter has thermal energy because the atoms are always moving.

CONVECTION: THE TRANSFER OF THERMAL ENERGY BY THE MOVEMENT OF THE PARTICLES FROM ONE PART OF A MATERIAL TO ANOTHER; TRANSFER OF THERMAL ENERGY IN A FLUID.

Heat Transfer. Energy transfer from a HOTTER object to a COOLER one.

Transfer of Energy Energy Transfer Energy is transferred from hotter object to colder object Examples? –Cooking pasta –Making ice –Making popcorn –Roasting.

-Heat is a measurement of the movement of particles of matter.

-The faster they are moving, the more heat or thermal energy they have -The faster they are moving, the more heat or thermal energy they have. -The slower the particles are moving the less heat it has.

How is heat transferred? There are three ways that heat is transferred from object to the next: conduction, convection, and radiation.

transfer of heat between substances that are in direct contact with each other. conduction

conduction Examples: grabbing the handle of a hot pan walking barefoot on concrete during the summer ironing clothes. conduction

thermal energy is transferred from hot places (areas of high thermal energy) to cold places (areas of low thermal energy). convection

Boiling water heat in a room the ocean convection

radiation heat is transmitted through empty space, with electromagnetic waves.
