Solution

Heat: Heat is a type of energy that is transferred from the higher temperature region to the lower temperature region.

  • The SI unit is Joule (J).
  • The phase change also happens due to heat.
  • The heat is calculated by an equation:

q=mCpT

where q is heat quantity, m is the mass of a material, Cp is either molar or specific heat capacity, and T is the temperature difference.
