How much heat is required to convert 20 g of ice at 0oC to water at the same temperature? (Specific latent heat of ice = 336 J g-1)
A
1.35 x 103J
B
5.38 x 103J
C
6.72 x 103J
D
7.06 x 103J
E
8.06 x 103J
Verified Correct Answer: C.
Physical Principles & Numerical Solution
The formula of specific latent heat of fusion is given by: Q = mL
: 20 X 336
= 6720 or 6.72 X 10\(^3\)
