Answer to Question #33596 in Physical Chemistry for muhammad zulqarnain

Question

Water is heated to boiling at a pressure of 1 atmosphere. When and electric current of 1 A from a 6 V supply is passed for a period of 300 seconds through a resistance in thermal contact with it, it is found that 0.798 g water is vaporized. Calculate the molar internal energy and enthalpy changes at the boiling point (373.15 K)
