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

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.

Thermal Energy is...

• The internal energy of an object

• The temperature of a solid object

• Heat transfer through a liquid

A system comprising a single phase is called a

• (a) closed system

• (b) open system

• (c) isolated system

• (d) homogeneous system

• (e) heterogeneous system.
