(a) An iron ball requires 5000 J heat energy to raise its temperature by `10^@`C. Calculate the heat capacity of the iron ball.
(b) If mass of ball is 1.1 kg, find the specific heat capacity of iron.

Text Solution

Verified by Experts

(a) Given, Q=5000 J , `Delta`t=`10^`C=K
Heat capacity C.=`("Heat enery required Q")/("rise in temperature "Deltat)`
or C.=`(500J)/(10 K)`=500 J `K^(-1)`
(b) Specific heat capacity of iron
=`("Heat capacity of ball")/("Mass of ball")=(500" "J" "K^(-1))/(10" "K)`=455 J `kg^(-1)K^(-1)`
