Problem 20P
The heat capacity, C, of an object is defined as the amount of heat needed to raise its temperature by 1 C°. Thus, to raise the temperature by ΔT requires heat Q given by
Q = C ΔT.
(a) Write the heat capacity C in terms of the specific heat, c, of the material. (b) What is the heat capacity of 1.0 kg of water ? (c) Of 25 kg of water?

Problem 20P
The heat capacity, C, of an object is defined as the amount of heat needed to raise its temperature by 1 C°. Thus, to raise the temperature by ΔT requires heat Q given by
Q = C ΔT.
(a) Write the heat capacity C in terms of the specific heat, c, of the material. (b) What is the heat capacity of 1.0 kg of water ? (c) Of 25 kg of water?
ANSWER:
Solution 20P:
Step 1 of 2:-
a)
We know that,
And here it is given as,
.
So, the heat capacity can be expressed in terms of the specific heat capacity as,
--------------(1)
