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).
Cup gets cooler while hand gets warmerThe flow of thermal energy (HEAT) always flows from warmer to cooler objects Ice gets warmer while hand gets cooler
Questions 1. What is thermal energy?How do you measure thermal energy? 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
How Are They Alike? Conduction Convection Radiation
How Are They Different? Conduction Convection Radiation
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 and the Mantle EQ: How is heat transferred?
CONVECTION CURRENTS AND THE MANTLE
Chapter 1-2 Convection and the Mantle. Heat always moves from warmer to cooler Three types of heat transfer Radiation – transfer of energy through.
Lesson 2 – Convection and the Mantle
WEEK20 PHYSICAL SCIENCE VOCABULARY. 1) THERMAL ENERGY Total amount of energy in all of the particles contained in a sample of matter.
Energy & Heat Transfer Energy is the ability to create change in a system. There are four main types of energy: Solar Motion Height Heat.
Conduction, Convection, and Radiation Add this to your table of contents. Turn to the next clean page and title it HEAT TRANSFER!
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.

THERMAL Energy Chapter 5.
Thermal Energy Heat.
Thermal Energy and Heat. Temperature The measure of how HOT or COLD and object is.
HEAT the transfer of thermal energy from hot objects to cold objects through collision of particles Units=Joules.
Radiation – the transfer of energy through space. Heat transfer by radiation takes place with no direct contact between a heat source and an object. Example.
Thermal Energy Conduction, Convection and Radiation.
Heat (PS 1-2) 1. I can define temperature as the measurement of thermal energy and describe the way it is measured. 2. I can trace how thermal energy.
Heat Transfer. Heat is the transfer of thermal energy between substances that are at different temperatures.
Is the measure of the average kinetic energy of the particles in a substance As the particles in a substance move faster and their kinetic energy becomes.
