- the entropy change in melting 5 kg ice at 0 degrees Celsius to water is equal to
A. 1.5 kj B. 1.5 J/K C. 1.5 cal/K D. None E. 1.5 kcal/K Heat required to melt 5 kg ice at 0 degrees celcisus to water is equal A. 400 cal B. None C. 400 kcal D. 400 J E. 400 KJ
- the entropy change in melting 5 kg ice at 0 degrees Celsius to water is equal to
A. 1.5 kj B. 1.5 J/K C. 1.5 cal/K D. None E. 1.5 kcal/K A. 400 cal B. None C. 400 kcal D. 400 J E. 400 KJ
- the entropy change in melting 5 kg ice at 0 degrees Celsius to water is equal to
A. 1.5 kj B. 1.5 J/K C. 1.5 cal/K D. None E. 1.5 kcal/K

Explanation / Answer

heat required to melt = mL

= 5*335*10^3 = 1675000J

= 1675000/4186 = 400 kCal

option C) is the correct answer

entropy change = 400 kCal /273 = 1.5 kCal/K

option E) is the correct answer
