1.	59. Of what physical significance is the difference between the two principal specific heat capacities and their ratio?
Answer» Heat capacityia heat required to raise the temperature of a substance by 1 degree Celsius. Specific heatis heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius. Let's assume substance'A'has specific heat of 1 KJ/kgK. Thespecific heat remains the sameif I take 5kg of 'A' or 10kg, because it is defined as per Kg of that substance. On the other hand heat capacitydepends on mass of the substance. If I have 5kg of that substance then heat capacity will be 5KJ/Kg, if I have 10kg then heat capacity becomes 10KJ/kg . Because more the mass, more it will take to raise the temperature by 1 degree Celsius.

Answer»

Heat capacityia heat required to raise the temperature of a substance by 1 degree Celsius.

Specific heatis heat required to raise the temperature of a unit mass of a substance by 1 degree Celsius.

Let's assume substance'A'has specific heat of 1 KJ/kgK. Thespecific heat remains the sameif I take 5kg of 'A' or 10kg, because it is defined as per Kg of that substance.

On the other hand heat capacitydepends on mass of the substance. If I have 5kg of that substance then heat capacity will be 5KJ/Kg, if I have 10kg then heat capacity becomes 10KJ/kg . Because more the mass, more it will take to raise the temperature by 1 degree Celsius.
