Energy and Calorimetry

constant-volume calorimeter used to measure the heat of reaction for combustion reactions

energy required to change the temperature of one gram of water by 1°C

device used to measure the heat exchanged between a system and its surroundings

study of heat exchange between a system and its surroundings

energy released during a chemical reaction

study of the flow of energy during chemical reactions or phase changes

energy stored as a result of a material's deformation

reaction in which energy is absorbed in the form of heat or light

capacity to do work

reaction in which energy is released in the form of heat or light

law that states that energy cannot be created or destroyed, only transformed from one type of energy to another type of energy; given as $\Delta U=q+w$

transfer of thermal energy

amount of heat needed to raise the temperature of a system by 1°C

net heat released or absorbed by a chemical reaction at a constant pressure

sum of all kinetic energy and potential energy of the particles in a system

system that does not exchange heat or matter with the surroundings

SI unit of energy; $1\;\rm J=1\;\rm{kg}\cdot\rm m^2/\rm s^2$

energy of an object in motion

energy of an object based on its position

amount of heat needed to raise the temperature of one gram of a substance by 1°C

part of the universe that is in immediate contact with a system

part of the universe that is being studied

measure of the average kinetic energy of the particles of a substance

kinetic energy of the particles that make up a system

science of energy changes associated with chemical reactions

energy that is transferred when a force acts on an object over a distance
