Question

An aluminum plate of mass 0.1 kg at 95oC is immersed in 0.5 litre of water at 20oC kept inside an insulating container and is then removed. If the temperature of the water is found to be 23oC, then the temperature of the aluminum plate is ___________ oC. (The specific heat of water and aluminum are 4200 J/kg-K and 900 J/kg-K respectively, the density of water is 1000 kg/m3)

Answer 1

23. They'll come to an equilibrium temp regardless.
