Question

In the activity, select H2. Click on the Run button, and observe the changes in entropy in the graph of molar entropy versus temperature. Observe the different phase changes the substance H2 undergoes, and classify the following phase changes according to whether entropy increases, entropy decreases, or entropy remains the same.

Drag the appropriate items to their respective bins. Energy increases, decreases or remains the same

H2 (s)---> H2(l) H2(l)-->H2(g) H2(g)--->H2(l) H2(l)----->H2(s) H2(g)---->H2(s) H2(s)--->H2(g)

Part D

You just calculated that the heat of fusion for chloromethane is 6400 J/mol. The heat of fusion for hydrogen is 120 J/mol. Which of the following account for this difference? The heat of fusion was 6.4x10^3 J x mol^-1

Check all that apply.

Explanation / Answer

Chloromethane has a higher molar mass than hydrogen.

Chloromethane experiences dipole-dipole interactions.
