WebJan 3, 2016 · In your case, two substances, let's say A and B, start at the temperature, 200∘C and they both absorb 150 J of heat. Moreover, they both have the same mass. If the specific heat of A is higher than the specific heat of B, you can say that it will take more energy to raise the temperature of A by 1∘C than to raise the temperature of B by 1∘C. WebTwo objects at different temperatures are brought into thermal contact and allowed to come into thermal equilibrium. Object 1 has heat capacity C1 and initial temperature T1. Object 2 has heat capacity C2 and initial temperature T2. When the combined system attains thermal equilibrium, the final temperature is Ts. Please show your work carefully
