The temperature of a body rises by `44^(@)C` when a certain amount of heat is given to it . The same heat when supplied to `22` g of ice at `-8^(@)C` , raises its temperature by `16^(@)C`. The water eqivalent of the body is `[Given : s_(water) = 1"cal"//g^(@)C` & `L_(t) = 80 "cal" //g, s_("ice") = 0.5"cal"//g^(@)C`]
