The specific latent heat of fusion of ice is 3.34 x 10^5 J/kg. How much energy is needed to melt 0.50 kg of ice at 0 degrees Celsius?

Answer and explanation

Correct answer: B. 167 kJ

  1. Step 1: J. Answer: 167 kJ. Why not the others: 334 kJ is for 1.0 kg; 1.5 x 10^-6 J divides mass by latent heat; 1.7 x 10^5 kJ is a unit slip.
