Question

We know that heat capacity depends upon mass of that substance being heated.
Then why the unit of heat capacity (J/K) which is Joule per Kelvin {does not have the specification of mass ????}
I want reasonable and professional answer.

Answer 1

Answer:

Specific heat capacity of a substance is the heat required to raise the temperature of unit mass of substance through 1

o

C or 1K, given by:

c=Q/mΔt ,

If m=kg (SI unit of mass), Δt=K (SI unit of temperature)

Q=joule (SI unit of heat energy)

Then, c=joule/kg×K= joule per kilogram per kelvin

This is the SI unit of specific heat.
