Question

the Latent heat of fusion of aluminum is 93 KCAL / kg at 660 degrees Celsius determine the amount of energy needed to melt 100 kg of aluminum at the melting point

Answer 1

Answer: 9300 kcal

Step-by-step explanation: Given: Latent heat of fusion of aluminum is 93 kcal/kg.

That is for melting 1 kg of aluminium at 660
`^0C` amount of heat required is = 93kcal

Thus for 100 kg of aluminium at 660
`^0C` amount of heat required is=
`(93)/(1)* 100=9300kcal`

Thus the amount of energy needed to melt 100 kg of aluminum at the melting point is 9300 kcal.
