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.

Reading the Tectonic Plate Map. pic Divergent Boundary: Where plates are spreading apart. Plates move away from each other as new rock is formed between.

Thermal Energy Transfer  Thermal Energy can be transferred by three methods Conduction Convection Radiation.

CPO Science Foundations of Physics

Thermal energy and Heat. Thermal energy Thermal energy is the total kinetic energy of all particles in a substance Measured in joules (J) This is not.

How ‘Heat’ Moves  Define “ Heat ”: Heat is the movement of thermal energy from a substance at a higher temperature to another substance at a lower temperature.

Thermal Energy Transfer “How Heat Moves”. What is Thermal Energy? Thermal energy (we often call this HEAT) is: The amount of movement of the particles.

Heat Transfer Conduction, Convection, & Radiation…oh my!!

Heat Transfer. Heat transfer Everything is made of molecules. When molecules gain energy they move faster and create more heat. (The faster the molecules.

Heat Not just hot or cold…but much, much more!!!.

Seconds Left: List & describe the three types of heat transfer.

What processes heat the atmosphere?

Conduction The transfer of energy as heat between particles collide within a substance or between two objects in contact Two objects of unequal temperature.

6.2 Transferring Thermal Energy. Conduction Transfer of thermal energy (TE) by collisions between the particles in matter Transfer of thermal energy (TE)

Transferring Thermal Energy!. Conduction Transfer of thermal energy by direct contact During collision, kinetic energy of faster moving particle transferred.

+ Conduction Conduction is heat transfer through direct contact.

+ Convection Convection is heat transfer between a solid object and the liquid or gas that is passing by it. NATURAL FORCED

+ Radiation Radiation is heat transfer in the form of electromagnetic waves that carry energy from one object to another.
