Question

One ton of litchi was cooled from 35$^\circ$C to 5$^\circ$C using a 5 ton refrigeration system in 3 hours. The amount of heat removed by the refrigeration system will be (given specific heat of litchi = 0.5 kcal/kg.$^\circ$C)

• A. 15000 kcal
• B. 30000 kcal
• C. 15 kcal
• D. 3000 kcal

Hint:

Always read the unit requirements of the final answer.
Since the options are in kilocalories (kcal) and the specific heat is provided in \( \text{kcal/kg}\cdot^\circ\text{C} \), you can perform the calculation directly without converting units to Joules.

Answer 1

The Correct Option is A
