Question

The heat of fusion of water is 6.01 kJ/mol. The heat capacity of liquid water is 75.3 J/mol ∙ K. The conversion of of ice at 0.00 °C to liquid water at 0.00°C requires ________ kJ of heat.
Question 10 options:

A)

16.7

B)

17.2

C)

6.01

D)

75.3

E)

Insufficient data are given.

Answer 1

C) 6.01

Melting ice at 0.00 °C to liquid water at 0.00 °C requires only the heat of fusion (no temperature change), so q = ΔHfus = 6.01 kJ per mole.
