Expert Answer

Step 1

Specific heat capacity:

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. It is also an example of an extensive property since its value is proportional to the size of the system being examined.

In ​SI units, specific heat capacity (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1Kelvin. It may also be expressed as J/kg·K. Specific heat capacity may be reported in the units of calories per gram degree Celsius, too.

Step 2

Molar heat capacity is the amount of heat capacity that is required to raise the temperature of per unit amount i.e., per mole of a substance by one degree Celsius (or Kelvin).

Although heat capacity is an extensive property,...
