1. Thermodynamics

2. Heat Transfer
Heat Transfer is the movement of heat energy from one material to another. There are three forms of heat transfer.

3. Heat transfer by conduction
Heat transfer in solids, liquids, gases, plasma (all states of matter)
Is a result of direct contact with a heat source
Is a result of movement of electrons
The pan is in direct contact with the heat source and allows heat to move from the coil to the pan.

4. Examples of Conduction
Cooking
Electricity
Melting ice in your hand

5. Heat transfer by convection
Heat transfer in fluids
A fluid refers to a liquid or a gas
Convection is responsible for our weather patterns
Using a heater, or radiator, during the winter to warm your house is an example of convection. The air is warmed and moves throughout the house.
Heat moving through water when it’s boiling is an example of convection.

6. Examples of Convection
Turning the heater on when it’s cold outside
Turning the air conditioning on when it’s hot outside
Convection currents in the ocean
Weather

7. Heat transfer by radiation
Heat transfer due to electromagnetic waves
Heat in the form of radiation comes off of things like campfires.
Heat from the sun is transmitted by electromagnetic waves.

8. Examples of Radiation
Solar radiation
Sitting near a campfire
