Content Temperature is a measure of heat intensity. Heat is a form of energy that flows from a region of higher intensity to a region of lower intensity.
Temperature is measured using a variety of thermometers.
In order to change the temperature of a substance, heat must be added or removed. The amount of heat required to change the temperature of one gram of a substance one degree Celsius is known as the specific heat capacity of that substance. This amount of energy is measured in joules. A total of 4.18 joules are required to raise the temperature of one gram of water one degree Celsius. The specific heat capacity of a substance is given in joules per gram-Celsius degree.
