Answer : The specific latent heat of fusion of ice is, 187.608 J/g
Explanation :
Formula used :
![Q=m* L_f](https://img.qammunity.org/2020/formulas/chemistry/middle-school/b3vavb36rnsfqckr9qs8v80p2ea7j8f19g.png)
where,
Q = heat supply = 863 KJ = 863000 J
conversion used : (1 KJ = 1000 J)
m = mass of the substance = 4.6 Kg = 4600 g
conversion used : (1 Kg = 1000 g)
= specific latent heat of fusion = ?
Now put all the given values in the above formula, we get the specific latent heat of fusion of ice.
![863000J=4600g* L_f](https://img.qammunity.org/2020/formulas/chemistry/middle-school/2jjhggdatix2cfpk8j5n7miy2uj6ugb8ix.png)
![L_f=187.608J/g](https://img.qammunity.org/2020/formulas/chemistry/middle-school/w2iyqd43xy6idmxqj4joub5d6se63zyvw4.png)
Therefore, the specific latent heat of fusion of ice is, 187.608 J/g
