Question

Which has more heat content 10g ice 0 degree or 10 g water 0 degree?

Answer 1

Answer:

External temperature in both the cases reamains constant. There is no exchange of heat between both the cases as ΔT = 0, i.e. T = constant also known as Isothermal process. As internal energy(U) is directly proportional to temperature(T), ΔU = 0. Also the process may be Adiabatic, i.e. Δq = 0, where, q = heat absorbed/lost.
