Average speed in km/h:
S = D/T
T = 10/60 hrs
= 0.1667
S = 10 / 0.1667
= 59.988 km/h
K (Potassium) has higher molar entropy than sodium.
The substance's condition has the most impact on the molar entropy. Compounds that are gases will have a far higher molar entropy than compounds that are liquids or solids because gases are much more widely dispersed. A substance's entropy rises as its molecular weight, complexity, and temperature rise. As the pressure or concentration decreases, the entropy likewise rises. Gas entropies are significantly higher than those of condensed phases. The highest entropy is in gases. This is due to the wide variety of microstates in which gases can reside. The amount of freedom that atoms in a substance have to disperse, migrate, and organize themselves randomly is referred to as entropy.

Answer:
A. Iodine
Explanation:
First 2 points describe it's physical properties. Even if we don't remember them, we can easily figure out the answer to be a non-metal. As, non-metals usually have lower bp and mp than metals.
Both Iodine and hydrogen exists as a 2 atom molecule in gas phase.
But only elements of group 17 (halogens) have 7 electrons in their outer shell.
Again, salts are usually ionic compounds, formed by atoms with a greater difference in their electronegativities. Hence, the one that forms bonds with a metal to form a salt readily can be a non- metal.
All these points indicate that the element must be iodine.
