The energy required to heat something is proportional to the mass and temperature change of the material. The proportionality constant is called specific heat. Photo by Johannes W on Unsplash. Specific heat is the amount of heat per unit mass needed to increase the temperature of a material by one degree Celsius or Kelvin. These three specific heat example problems will show how to find the specific heat of a material or other information involving the specific heat.

A body with mass 2 kg absorbs heat calories when its temperature raises from 20 o C to 70 o C. What is the specific heat of the body? Known :. Wanted : The specific heat c. Solution :. How much the heat capacity of 2 kg water…. Wanted : Heat capacity C.
We consider isolated systems, unless otherwise stated, so that no heat is lost to the environment and the principle of conservation of energy can be applied to work out the answer. If the liquids are removed from their recipients and mixed, the final temperature would be around:. Comments: It is important to observe the SI units. The mass is in kg and the heat energy in J. Normally the temperature is converted into K, but because we are taking the difference or the variation , it doesn't matter what units are used if kelvin or celsius.
