Reviewing Heat (Thermal) Energy
Heat (thermal) energy is created by the movement of particles (atoms) that produces heat.
Heat (thermal) energy increases as temperature increases because as temperature increases, atoms move faster (have more kinetic energy)
Transfer of Heat (Thermal) Energy
Heat (thermal energy) is transferred from one object to another when the objects are at different temperatures.
The amount of heat (thermal energy) that is transferred when two objects are brought into contact depends on the difference in temperature between the objects.
Heat is transferred only when two objects are at different temperatures
Thermal energy always moves from warmer to cooler objects
The warmer object loses thermal energy and becomes cooler as the cooler object gains thermal energy and becomes warmer.
Energy will continue to move from a warmer object to a cooler object until both have the same temperature.
Heat Transfer can occur in three ways:
Conduction is the transfer of heat by direct contact (particles collide)
Conduction occurs most easily in solids and liquids
