Question

The chemical equation and thermodynamic data for the melting of tungsten are given above. Based on this information, which of the following provides the best predictions correc whether a sample of pure tungsten will melt at 3723 K?
A. The sample will not melt because T > H/s
B. The sample will not melt because T< H/s
C. The sample will mel because T>
D. The sample will mel because T

Answer 1

Answer:

C. The sample will melt because T < H/s

Explanation:

The tungsten is a pure form of metal. It has a melting point higher than 1650 C. The pure sample of tungsten will met at 3723 K because the change in H over change in S is greater than T. The tungsten will go to a transition from solid to liquid and will melt completely.
