Answer:

Q = 832 kJ

Step-by-step explanation:

It is given that,

Mass of the water, m = 2.5 kg

The latent heat of fusion, L = 333 kJ/kg

We need to find the heat needed to melt water at its melting point. The formula of heat needed to melt is given by :

Q = mL

$Q=2.5\ kg* 333\ kJ/kg\\\\Q=832.5\ kJ$

or

Q = 832 kJ

So, the heat needed to melt the water is 832 kJ.
