Different substances have different densities. Fe These can then be used in calculations involving volume and mass of a material. Specific gravity is related to density. For a given substance it is the ratio of the density of that substance to the density of water. Heat and Temperature Heat and temperature are related, but different.
Heat is a form of energy that can flow from a warmer object to a colder object.
The flow of heat causes the warmer object to get cooler, making the temperature of that object lower. The cooler object getting the heat becomes warmer, and its temperature rises. So heat and temperature are related, but not the same. Temperature is measured in degrees. In science, the most common temperature scale is the Celcius or Centigrade scale.
