mc₁ΔT₁=mc₂ΔT₂
c₁ΔT₁=c₂ΔT₂
c₁(95-30)=c₂(292-30)
c₂=c₁(95-30)/(292-30)=
=840•65/262 = 208.4 J/kg•°C.
Two bars of identical mass are at 30 °C. One is made from glass and the other from another substance. 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 95 °C, while the other bar reaches 292.0 °C. What is the specific heat capacity of the other substance?
