What is heat?

• the amount of thermal energy in an object

• an object's internal kinetic energy

• the transfer of thermal energy from one object to another

• the amount of energy needed to raise the temp of an object

The 1st law of Thermodynamics

• Energy can not be created or destroyed. It just changes forms.

• Energy can only be created by the sun

• Some energy is lost to the environment.

Specific Heat

• the amount of energy it takes to raise one gram of a substance by one degree Celsius

• The internal energy of an object

• The measure of the kinetic energy of an object's molecules

Conduction

• The transfer of thermal energy through solids

• The transfer of thermal energy through liquids and gases

• The transfer of thermal energy as electromagnetic waves

Convection

• The transfer of thermal energy through liquids and gases

• The transfer of thermal energy through solids
