Thermal Energy
11
temperature:is a measure of the average value of the kinetic energy of the molecules in random motion.
thermal energy:the sum of the kinetic and potential energy of all the molecules in an object.
heat:thermal energy that is transferred from one object to another when the objects are at different temperatures.
conduction:occurs when the particles in a material collide with neighboring particles.
radiation:occurs when energy is transferred by electromagnetic waves.
convection:transfer of the thermal energy by the movement of molecules from one part of a material to another.
conductor:any material that easily transfers heat.
specific heat:the amount of heat needed to raise the temperature of 1 kg of the substance by 1 degree C.
thermal pollution: the increase in the temperature of a body of water caused by adding warmer water.
heat engine:a device that converts thermal energy into mechanical energy.
internal combustion engine:fuel burns in a combustion chamber inside the engine.
