HEAT TRANSFER - the transfer of thermal energy between substances due to a difference in their temperature
THERMAL ENERGY is the total of all the kinetic and potential energy of all the particles in a substance.
TEMPERATURE is a measurement of the average kinetic energy of the molecules in an object. It is measured with a thermometer. It is a measurement of the internal energy contained in an object.
As the temperature increases, so does thermal energy (because the kinetic energy of the particles increased).
The flow of thermal energy (HEAT) always flows from warmer to cooler objects Cup gets cooler while hand gets warmer Ice gets warmer while hand gets cooler
Questions 1. What is thermal energy? 2. How do you measure thermal energy? 3. What is heat? 4. How does thermal energy flow?
Insert video clip – conduction, convection & radiation
CONDUCTION is the transfer of heat through a material by direct contact.
CONVECTION is the transfer of heat in a fluid (gas or liquid) as a result of the movement of the fluid itself
RADIATION is the transfer of heat via electromagnetic waves through space

Conduction, Convection, or Radiation? The spoon is too hot to touch after sitting in the hot soup.
Conduction, Convection, or Radiation? The moon’s surface becomes hot.
Conduction, Convection, or Radiation? Your feet hurt after walking barefoot across the beach
Conduction, Convection, or Radiation? Bacon cooks in the frying pan
Conduction, Convection, or Radiation? The room becomes warm when the furnace is turned on
Convection Currents Heat is always transferred from warmer substance to a cooler substance. Write down some examples of this concept:
16-2 Heat Transfer (pages 548–551) 1. Describe how temperature is measured. 2. Identify three ways in which heat is transferred. 3. Explain how heat is.
Heat Transfer. Lesson Goals Students will: Explain how heat moves from one place to another including how cooler materials can become warmer and vice.
I. WHAT IS TEMPERATURE? We don’t use the terms hot and cold often in science because they are relative terms: They could mean different things depending.
Thermal and Chemical Energy. Thermal Energy Thermal Energy Thermal energy is kinetic energy because molecules are in motion. Temperature Temperature =
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. Heat is the transfer of thermal energy between substances that are at different temperatures.
Additional Notes. What is the total energy of motion in the molecules of a substance? Thermal Energy.
IT’S A HEAT THING. CONVECTION, RADIATION, AND CONDUCTION.
Heat Transfer Thermal energy Temperature is the average amount of energy of motion of each particle of a substance. Thermal energy is the total energy.
