Answer #1

The conversion of solid to liquid is called melt.

The enthalpy or heat required for this process is called heat of fusion ( ΔHfusion) .

The enthalpy change when 1kg ice melts is 334 KJ.

so option C is the correct answer.

The detail explanation is shown below.

Ah susion = 6.009 kJ/mole. the enthalpy required for conversion I mole of solid in to liquid is 6.009 KI. Imola of ice (H2O)
