Find the change in the internal energy of

2\text{ kg}

of water as it is heated from

0^{\circ}\text{C}

4^{\circ}\text{C}

. The specific heat capacity of water is

4200\text{ J kg}^{-1}\text{K}^{-1}

and its densities at

0^{\circ}\text{C}

and

4^{\circ}\text{C}

are

999.9\text{ kg m}^{-3}

and

1000\text{ kg m}^{-3}

, respectively. Atmospheric pressure is

10^5\text{ Pa}
