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

The correct answer is C. 6.72 x 103J

The formula of specific latent heat of fusion is given by: Q = mL

: 20 X 336

= 6720 or 6.72 X 10\(^3\)
