Thermodynamics

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.

2nd law of thermodynamics

• Every time energy changes form, some of it is lost to the environment

• Energy can't be created or destroyed

• All energy generates heat
