# How much heat is released when 2.00 kg of aluminum solidifies? How many kJ is this?

May 2, 2017

As latent heat of fusion is equal to latent heat of freezing as the melting point and the freezing point is same.

The energy released

$\text{latent heat of fusion"/x xx "amount} \left(x\right)$

Here x is used to represent unit of quantity. Like it can mole, g, kilograms and so on

latent heat of fusion of aluminium = $\text{398kj/kg}$

$\text{398kj"/cancel("kg") * 2cancel("kg") = "796kj}$
