1st Law of Thermodynamics

• Energy has quality and quantity and the process occurs in the direction of decreasing quality

• If two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other

• Energy can not be created or destroyed, it just changes forms

2nd Law of Thermodynamics

• Energy has quality and quantity and the process occurs in the direction of decreasing quality

• If two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other

• Energy can not be created or destroyed, it just changes forms

0th Law of Thermodynamics

• Energy has quality and quantity and the process occurs in the direction of decreasing quality

• If two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other

• Energy can not be created or destroyed, it just changes forms

Define ΔH

• Change in Specific Heat; Heat by one Degree Celsius

• Change in Temperature; the energy we calculate; Degree Celsius

• Change in Enthalpy; the energy/heat we calculate

• Change in Time; time travel
