Question

How much heat is released to freeze 47.30 grams of copper at its freezing point of 1,085°C? The latent heat of fusion of copper is 205.0 J/g.

Answer 1

-9697

Step-by-step explanation:

thats the answer

Answer 2

=9696.5J

Step-by-step explanation:

The latent heat of fusion of a unit mass of copper is the heat released when it changes from its molten state to solid state of the heat absorbed to melt it.

The total energy released is calculated using MLf where M is the mass of the copper and Lf is the latent heat of fusion.

=mLf

=47.30 grams×205.0J/g

=9696.5J
