Question

prove that a thermal capacity for unit mass of a body is equal to the specific heat of its material​

Answer 1

Let thermal capacity be c’

Specific heat capacity of a body be c

As c’=Q/T( change in temp) ——eq(1)

Q = heat energy

As Q =mcT —————-eq(2)

Where m = mass of the body

And T is change in temp

Put value of Q in eq (1)

C’=mcT/T

C’=mc...

Hence proved.
