Conduction: In heat, energy transfer from particle to particle within certain m aterials, or from one material to another when the two are in direct contact.
Convection: A means of heat transfer by movement of the heated substance itself, such as by currents in a fluid.
Radiation:Energy trasmitted by electromagnetic waves.The particle given off by radioactive such as uranium.
joules:The SI unit of work and of all other forms of energy.One joule of work is done when a force of one newton is exerted on an object moved one meter in te direction of the force.
Calories:A unit of heat.One calorie is the heat required to raise the temperature of one gram of water one Celsius degree.
First law of Thermaldanamics: Heat added to a system is transformed to an equal amount of soe other form of energy; a version of the law of energy conservation.
