Physics · Secondary 3 · Hard · Latent heat

A 0.40 kg block of ice at 0°C is completely melted by an electric heater that supplies energy at a rate of 160 W for 5.0 minutes. What is the specific latent heat of fusion of ice from this experiment?

$1.2 \times 10^5\,\text{J/kg}$
$4.8 \times 10^4\,\text{J/kg}$
$6.0 \times 10^5\,\text{J/kg}$
$3.0 \times 10^4\,\text{J/kg}$
