Term | Definition |
---|---|
temputure | is a measure of an average value of the kinetic energy of the molecules in a random motion |
thermal energy | the sum of the kinetic and potential energy of all molecules in an object |
heat | transfer of thermal energy from one object to another when the objects are at different temputers |
conduction | occurs when the particles in a material collide with huiboring particles |
radiation | thermal energy transferred by radiation occurs when energy is transferred by electromagnet waves |
convection | this transfer of thermal energy by the movement of atoms or molecules from one part of material to another |
conductor | any material that transfers thermal energy |
specific heat | of a material is the amount of thermal energy needed to raise the temputure of 1kg of the material by 1 c |
thermal pollution | discharge of heated liquid into water |
