0.1428 calorie #gm^-1 C^-1#

Explanation:

With in a minute heat energy supplied by the burner will be #(H)# = #(20*60)# J or #1200# J or #(1200/4)# i.e #285.714# Calorie

So,if the solid mass of #m# increases it's temperature by #theta# due to this amount of heat energy,we can write,

#H=mstheta# (where s is its specific heat capacity)

Given. #m=25# gm and, #theta = 80#

So,we get,s = 0.1428 CGS units
