What quantity of heat is required to convert 20 g of ice at 0 ºC to water at the same temperature? (Specific latent heat of ice = 336 Jg-1)
- A. 7.06 x 103J
- B. 5.38 x 103J
- C. 6.72 x 103J
- D. 1.35 x 103J
Correct Answer: C. 6.72 x 103J
Explanation
quantity of heat = mass * Specific latent heat → 20 * 336
quantity of heat = 6720j or 6.72 x 10\(^{3}\)J
