31.0 m of water is converted into 1671 m³ of steam at atmospheric pressure and 100°C temperature. The latent heat of vapourisation of water is 2.3 x 10° J/kg. If 2.0 kg of water be converted into steam at atmospheric pressure and 100°C temperature, then how much will be the increase in its internal energy? Density of water is 1.0 x 10* kg/m², atmospheric pressure = 1.01 x 10% N/m2
