Question
An aluminium object with a mass of 4.97 kg
and at a temperature of 26.8 °C comes to
thermal contact with a 9.98 kg copper object
which is initially at a temperature of 85.3 °C.
What is going to be the equilibrum
temperature of the two objects? Neglect heat
transfer between the objects and the
environment. The specific heats are: CAI =
900 J/kg°C and ccu = 387 J/kg°C.
