Passage
The molar heat of fusion is the amount of heat necessary to melt (or freeze) 1.00 mole of a substance at its melting point at a constant pressure. The molar heat of fusion for water is 6.02 kilojoules per mole (kJ/mol).
The equation for molar heat of fusion is:
q = ΔHfus(mass/molar mass)
In this equation, q is the total amount of heat involved, ΔHfus represents the molar heat of fusion (this value is a constant for a given substance), and (mass/molar mass) represents the number of moles of a given substance.
The following table lists molar heats of fusion, boiling points, and melting points for several elements.

In this equation, q is the total amount of heat involved, ΔHfus represents the molar heat of fusion (this value is a constant for a given substance), and (mass/molar mass) represents the number of moles of a given substance.
The following table lists molar heats of fusion, boiling points, and melting points for several elements.
Q. It was hypothesized that the heat of fusion will increase as the boiling point increases. Based on the data in the table, which of the following pairs of elements support(s) this hypothesis?
I. Nickel and iron
II. Water and calcium
III. Silver and iron
I. Nickel and iron
II. Water and calcium
III. Silver and iron
- a)I only
- b)III only
- c)II and III only
- d)I, II, and III
Correct answer is option 'C'. Can you explain this answer?

To answer this question, compare the boiling points and molar heats of fusion for each of the pairs of elements:
I. Nickel and iron—the boiling point of iron is higher than the boiling point of nickel, but the molar heat of fusion is lower for iron than it is for nickel. Roman numeral I does not support the hypothesis, so eliminate answer choices A and D.
II. Water and calcium—the boiling point of water is lower than the boiling point of calcium, and the molar heat of fusion is lower for water than it is for calcium. Roman numeral II supports the hypothesis, so eliminate answer choice B.
The process of elimination leaves you with answer choice C, but if you evaluate Roman numeral III you will see that it also supports the hypothesis.
I. Nickel and iron—the boiling point of iron is higher than the boiling point of nickel, but the molar heat of fusion is lower for iron than it is for nickel. Roman numeral I does not support the hypothesis, so eliminate answer choices A and D.
II. Water and calcium—the boiling point of water is lower than the boiling point of calcium, and the molar heat of fusion is lower for water than it is for calcium. Roman numeral II supports the hypothesis, so eliminate answer choice B.
The process of elimination leaves you with answer choice C, but if you evaluate Roman numeral III you will see that it also supports the hypothesis.
