Specific heat of water is 4.186 J/g/C. The heat required to raise the temperature by

$\Delta T$ is
$Q=ms \Delta T$

Here
is mass of water being heated,
s=4.186 J/g/C. specific heat of water and
$\Delta T$ change in temperature.

Here
$m=2.5kg=2500g,\Delta T=55-18.5=36.5$ .

Heat energy required is
