The First Law of Thermodynamics states...

• When energy is converted from one form to another, some usable energy is converted into heat that disperses into the surroundings

• Energy cannot be created or destroyed

• Biological systems are open systems that exchangeenergy with their surroundings

The Second Law of Thermodynamics states...

• Energy cannot be created or destroyed

• Biological systems are open systems that exchange energy with their surroundings

• When energy is converted from one form to another, some usable energy is converted into heat that disperses into the surroundings

The measure of the disorder or randomness of energy

• Entropy

• Free Energy

• Heat

• Enthalpy
