Q. Two bars of identical mass are at 29 °C. One is made from glass and the other from another substance. The specific heat capacity of glass is 840 J/ (kg • C°). While identical amounts of heat are supplied to each, the glass bar reaches a temperature of 95 °C, while the other bar reaches 276.0 °C. What is the specific heat capacity of the other substance?
