The main reason for making the copper calorimeter (used in bomb calorimeter) silvery white and shining/polished is to___________________?
Correct answer: B. Avoid radiation heat loss
- A. Minimise its corrosion
- B. Avoid radiation heat loss
- C. Make it look attractive
- D. None of these
Explanation
A polished, silvery surface has low emissivity, so it radiates and absorbs less heat. This reduces radiation heat loss and improves the accuracy of the bomb calorimeter.
