Answer to Question #283232 in Physical Chemistry for Manish

Question

Calculate the total heat required to raise the temperature of 1 kg of tin from 30C to 300C. 

Tin remain in molten state at 300C. 

Given data for tin is 

Melting point = 231.8C 

Molecular weight = 118.7g 

Latent heat of fusion = 1720 kcal/kg mole 

Heat capacity (Cpm) of solid tin = Cp = 5.05+0.0048T kcal/kg mole K, T is in K. 

Heat capacity of liquid tin between melting point and 300C = 7.64 kcal/kg mole K.

Answer 1

Total heat required =3,750kJ
