For water, the latent heat of fusion is given as which value?
A9.33 times ten to the four
B3.33 times ten to the five
C3.33 times ten to the four
D9.33 times ten to the five
Answer & Solution
Correct answer: B. 3.33 times ten to the five
1. Latent heat of fusion is the energy to melt one kilogram at the melting point.
2. For water that figure is quoted directly.
3. The latent heat of fusion for water is 3.33 times ten to the five joules per kilogram.
4. The latent heat of vaporisation is 22.6 times ten to the five.
