ABOUT THERMAL ENERGY
Thermal energy is the energy that comes heat. This heat is generated by the movement of tiny parti- cles within an object. The faster these particles move, the more heat is generated. Stoves and matches are ex- amples of objects that conduct thermal energy. Interesting Thermal Energy Facts:
■Thermal energy is a purt of the total energy of any object.
■Thermal energy is retated to the temperature of an object.
■ The joule is the unit used to measure thermal energy.
■Unlike other forms of energy, thermal energy is difficult to convert to other forms of energy.
■When thermal energy is transferred from or to an object, it is called heat.
■Since heat is known as a process, objects cannot contain heat. Objects contain thermal energy.
■In order to convert thermal energy into other forms of energy, a machine such as an engine is needed,
■Unlike other forms of energy. the amount of thermal energy is not dependent upon the amount of work an object performs.
■ As heat from Earth is lost to space, it is replaced by heat brought by the Sun.
HEAT TRANSFER
■ Although he was not the first to use the term thermal energy, James Joule receives credit for being the first to discuss the loss and gain of heat.
■ When you add ice to a warm drink, some of the drinks' thermal energy is transferred to the ice which makes the drink cooler.
■ Heat and temperuture are not the same thing because temperature is related to how hot or cold something is.
■Heat energy can be transferred by three ways: convection, conduction, and radiation.
■Conductors, such as metals, are objects that allow thermal energy move easily through them.
