Calculate the increase in the internal energy of

10\text{ g}

of water when it is heated from

0^{\circ}\text{C}

to

100^{\circ}\text{C}

and converted into steam at

100\text{ kPa}

. The density of steam =

0.6\text{ kg/m}^3

. Specific heat capacity of water =

4200\text{ J/kg}\cdot^{\circ}\text{C}

and the latent heat of vaporisation of water =

2.5 \times 10^6\text{ J/kg}

.
