Heat: transfer of energy due to contact
Thermal energy: the amount of energy in an object directly related to temperature
Temperature: the measure of internal energy of an object due to particle motion
Heat Capacities
Specific heat capacity: amount of heat needed to raise the temperature of one gram of a substance by 1 degree Celsius
Heat capacity: amount of heat needed to raise the temperature of one gram of a sample by 1 degree Celsius
Calorimetry: The science of measuring the heat of chemical reactions.

| Usually uses an insulator, like styrofoam, to prevent heat loss |
Types of Systems
Open: a system where both matter and energy may be transferred between the system and the surroundings
Closed: a system where energy may be transferred between the system and the surroundings
Isolated: a system where neither matter nor energy can be transferred between the system and the surrounding
