kelvin

SI unit for temperature.

temperature

measure of the average kinetic energy of the molecules in a system.

heat

the transfer of energy due a difference in temperature.

internal energy

The sum of all energies of a system.

thermal expansion

The change in size or volume of an object that is subject to a temperature change.

average kinetic energy

conduction

heat transfer between two objects through direct contact.

convection

heat transfer via movement of liquid or gas.

radiation

heat transfer via electromagnetic waves (no medium necessary).

zeroth law of thermodynamics

if two objects are each in thermal equilibrium with a third object, then the first two objects will be in thermal equilibrium with each other.

first law of thermodynamics

energy can not be created or destroyed, only converted from one form to another.

isothermal process

process where temperature remains constant.

adiabatic process

process where no heat enters or leaves the system.

isobaric process

process where pressure remains constant.

isochoric process

process where volume remains constant.

second law of thermodynamics

The entropy of a system can only increase or remain constant.

87th law of thermodynamics
