Question
14) Two objects of the same material make up a system that is thermally isolated from its surroundings.
The cold object has an initial temperature of 10 C and the hotter object has an initial temperature of 93 C.
What is the equilibrium temperature of the system, assuming that no phase changes take place for either object? (The hot object has a mass that is 3 times that of the cold object.)

What is the equilibrium temperature of the system, assuming that no phase changes take place for either object? (The hot object has a mass that is 3 times that of the cold object.)Explanation / Answer
heat lost by hot object = heat gained by cold object
ie., m x 3 c x ( 10 - t) = m x c ( t -93 ) , whre 't' is ther resultant temperature.
solving you get t = 30.75 degree C
