How much heat energy is required to change \(2\) \(kg\) of ice at \(0°C\) into water at \(20°C\)? (Specific latent heat of fusion of water \(= 3,34,000 J/kg\), Specific heat capacity of water \(= 4200\) JKg1K1)
  
The letter \(C\) denotes
By applying the known values in the formula,
 
The required heat energy is  \(J\).
