1 kg of water at 100ºC is converted into steam at 100ºC by boiling at atmospheric pressure. The volume of water changes from 1.00 × 10^–3 m³ as a liquid to 1.671 m³ as steam. The change in internal energy of the system during the process will be (Given latent heat of vaporization = 2257 kJ/kg. Atmospheric pressure = 1 × 10⁵ Pa)
