Energy 
Defined as the capacity yo do work or transfer heat.
Work 
The energy used to cause an object to move against a force
Heat 
The energy used to cause the temperature of an object to incraese
Temperature 
Measure of the thermal energy
System 
The collective substances in the reaction in the reaction such as the reactants and products
Surroundings 
Everything around the reaction
Exothermic Reaction 
If the energy required to break the bonds is less than the energy released when the bonds are formed, there is a release of net energy.
Endothermic Reaction 
If the energy required to break the bonds is larger than the energy released when the bonds are formed,
Open System 
matter and energy can be exchanged with the surroundings.
Closed System 
systems that can exchange energy but not matter with their surroundings
Isolated System  
neither energy nor matter can be exchanged with the surroundings.
