Some element can be either solid or liquid. at the melting point, the liquid has 8 × 10-22 j more enthalpy per atom than the solid. the liquid also has 6 × 10-24 j/k more entropy per atom than the solid.

1) what is the latent heat per mole of the phase transition between the solid and the liquid?

? j/mole

2) at what temperature does the melting transition occur?

tmelting = ? k

481.76 J/mol

133.33 K

Explanation:

= Avogadro's number =

Change in enthalpy is given by

Entropy is given by

Latent heat of fusion is given by

The latent heat of fusion is 481.76 J/mol

Melting point is given by

Melting occurs at 133.33 K

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
