| energy | the ability to do work or transfer heat |
| work | the movement of an object against a force |
| heat | the flow of energy from a warmer object to a colder one |
| kinetic energy | energy an object has due to it's motion |
| potential energy | energy an object has due to it's composition or position |
| Joule | The SI unit of energy (1 kg m^2/s^2) |
| calorie | unit of energy that is equal to the amount of energy needed to raise the temperature of 1g of water 1 degree Celsius |
| internal energy | the total energy possessed by a system |
| endothermic | describes a process where heat is absorbed by the system from the surroundings |
| exothermic | describes a process where heat is released from the system to the surroundings |
| state function | a property that is determined by the system's state, not how it got there. ex. temperature |
| enthalpy | E + PV |
| intensive property | a property that is independent of the amount of material (ex. density) |
| extensive property | a property that depends on the amount of material (ex. mass) |
| enthalpy of reaction | enthalpy change associated with a chemical reaction (the amount of energy released or absorbed by a chemical reaction) |
| calorimeter | a piece of equipment used to measure the amount of heat given off during a process |
| calorimetry | an experimental procedure for measuring heat given off during a process |
| heat capacity | the amount of heat required to raise the temperature of an object 1 degree Celsius |
| molar heat capacity | the energy needed to raise the temperature of 1 mole of a substance by 1 degree Celsius |
| specific heat | the energy needed to raise the temperature of 1g of a substance 1 degree Celsius |
| enthalpy of formation | enthalpy change associated with a formation reaction (the amount of energy released or absorbed when a substance is formed from it's elements) |
| standard enthalpy of reaction | enthalpy change associated with a chemical reaction (the amount of energy released or absorbed by a chemical reaction at 1 atm and 25C) |
| standard enthalpy of formation | enthalpy change associated with a formation reaction (the amount of energy released or absorbed when a substance is formed from it's elements at their standard states) |
