Question

: How much energy is needed to melt 6.37 kg of aluminum at its melting point?

Answer 1

Latent heat of fusion is the energy needed to convert 1 kg of substance in solid s
state to liquid state at its melting point

Latent Heat of Fusion of Aluminum =396 kJ/Kg
So one kg Aluminium need 396 KJ energy to melt at melting point
Since 6.37 Kg Aluminium is there;
the energy required = 396 KJ/Kg *6.37 kg = 2522.52 KJ

Answer = 2522.52 KJ
