A copper block of mass `60kg` is heated till its temperature is increased by `20^(@)C` Find the head supplied to the block specific head capacity of `= 0.09 cal g^(-1)^(@)C^(-1) `

Text Solution

Verified by Experts

The head supplied is `Q = bs delta theta `
`= (60g)(0.09 cal g^(-1)^(@)C^(-1))(20^(@)C= 108 cal`
The quantity ms is called the head cupacity of the body .Its unit is `JK^(-1)` The mass of water having the same head capacity as a given body is called water wquiualent of the body
