Question:

A mug contains 0.5 kg of coffee (properties: density = 1000 kg/m3, cv = 1 kJ/kg.K) at 20oC.
(a) Determine the amount of heat (in kJ) necessary (there is no work transfer) to raise the temperature to 70oC.
(b) Amount of work (kJ) necessary to move it up by a height of 10 m.
(c) Amount of work (kJ) necessary to accelerate the mug from 0 to 30 m/s. Assume the mug to have no mass. Also, for the last two parts assume the mug to be adiabatic.
