Out of the following substances, one ton of ______________ will store the maximum heat for a rise of 30°C in temperature ?
Correct answer: C. Water
- A. Steel
- B. Lignite
- C. Water
- D. Lime stone
Explanation
Heat stored for the same mass and temperature rise is mC_pΔT, so the material with the greatest specific heat stores the most heat. Water has a much higher specific heat than steel, lignite, or limestone.
