Calculate the increase in the internal energy of 10 g of water when it is heated from 0°c to 100°c and converted into steam at 100kpa

Question

The density of steam is 0.6 kg/m ^3 Specific heat capacity is 4200 J /kg/°c and the lateent of vaporization of water  is 2.25×10^6 j/kg

Answer 1

Given:
Mass of water, m = 10 g = 0.01 kg
Pressure, P = 10⁵ Pa
Specific heat capacity of water, c = 1000 J/Kg °C
Latent heat, L = 2.25×10⁶ J/Kg
Δt=Change in temperature of the system=100°C=373 K

∆t=Change in temperature of the system=100°C=373 K

∆Q = Heat absorbed to raise the temperature of water from 0°C to 100°C + Latent heat for conversion of water to steam
