Question 6, When 1.0 kg of ethanol at 25°C changes from the liquid to the gas phase at atmospheric pressure. The volume of that ethanol changes from 1.27 x 10-3 m to 1.35 m². Given the latent heat of vaporization of ethanol is 838 J/g and atmospheric pressure P = 1.01 x 10*Pa. Find (a) the minimum amount of heat must be added to boil the ethanol. (b) the work done by the system during the vaporization process. (e) change in the internal energy of the liquid ethanol. (d) change of intermal energy when the gas phase ethanol is condensed back to liquid state. Provide justification to you answer.
