Calculate the change in internal energy of 2kg of water at 90 Degree Celsius when it is changed to 3.30m^3 of steam at 100 Degrees Celsius. The whole process occurs at atmospheric pressure. The latent heat of vaporization of water is 2.26 X 10^6 J/kg.
(A) 4.27 MJ
(B) 3.43 kJ
(C) 45.72 mJ
(D) 543.63 J
