Heat would be required : 1,670 J

<h3>Further explanation</h3>

Given

mass of H₂O=5 g

Required

Heat to melt

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Lf=latent heat of fusion

The heat of fusion for water at 0 °C : 334 J/g

Input given values in formula :

$\tt Q=5\times 334=\boxed{\bold{1,670~J}}$
