it is more obvious that you have problem in WATER EQUIVALENT so here it is
It is the amount of water which requires the same amount of heat for the same temperature rise as that of the object
ms T = mw Sw T
mw =ms/sw
In calorie sw = 1
mw = ms
mw is also represent by W
so W = ms.
so if u have answer of this question i will also give u solution of this question..
