Two bars of equal mass are at 32°C. One is made from glass and the other from another material. The specific heat capacity of glass is 840 J/(kg•C°). When identical amounts of heat are supplied to each, the glass bar reaches a temperature of 94°C, while the other bar reaches 267°C. Obtain the specific heat capacity of the other material?
