work transfer of energy through motion
temperature measure of the average kinetic energy of the particles in a sample of matter
thermal pollution may occur as an effect of waste heat on the environment
energy the ability to cause change
specific heat amount of energy it takes to raise the temperature of 1 kg of a material 1 Celsius degree
heat energy that flows from something with a higher temperature to something with a lower temperature
potential energy stored energy
kinetic energy energy in the form of motion
law of conservation of energy energy may change from one form to another but it cannot be created or destroyed under ordinary conditions
