How much heat is required to convert 0.3 kilogram of ice at 0 degrees celsius to water at the same temperature

Question

A. 100,375 J
B. 167,292 J
C. 334,584 J
D. 450,759 J

Answer 1

A 100,375

Answer 2

Converting 0 degree C ice to 0 degree C water involves adding enough heat to the system to overcome the latent heat of fusion.

The latent heat of fusion of ice is about 3.35 E5 J/kg.
Using the formula,
Q = m*L
where Q is the heat energy, m is the mass of the ice, and L is the latent heat of fusion of ice,
Q = (.3 kg) * (3.35 E5 J/kg)
Q = 100500 Joules

Although my answer does not exactly match any of the choices, it is closest to answer (A).
The reason for the discrepancy of the answers, is because I probably used an every so slightly different value for the latent heat of fusion than the person who made the problem.

Answer 3

B.167,292 J
