Calculate the amount of energy released by the freezing of 13.3 g of water

We can calculate for the amount of heat released using the formula:

ΔH = ʎ m

where,

ΔH = heat released

ʎ = latent heat of fusing for water = - 333.55 J/g

m = mass of water = 13.3 g

Calculating:

ΔH = ( - 333.55 J/g) * 13.3 g

ΔH = - 4,503 J = 1.08 cal
