ABSTRACT

This chapter gives a brief introduction to energy terms: temperature, heat, and power. Temperature is a measure of how hot or cold an object is. Fahrenheit is the temperature scale used for British units while Celsius is the metric temperature scale. Centigrade is the same as Celsius. Temperature is a measure of how hot or cold an object is. Fahrenheit is the temperature scale used for British units while Celsius is the metric temperature scale. Centigrade is the same as Celsius. There is a limit on how cold an object can become. Heat is thermal energy defined as energy in transition due to a temperature difference. A unit of heat is the British thermal unit, (Btu). One Btu is the amount of heat required to raise one pound of water one degree Fahrenheit. It takes 3413 Btu’s to equal 1 kilowatt- hour. Power is defined as energy per unit time, for example, Btu’s per hour.
