Question:
Some statements about heavy water are given below. Which of the following statements are true?
Some statements about heavy water are given below. Which of the following statements are true?
Show Hint
Heavy water is often used in reactors because it can slow down neutrons without absorbing them.
Updated On: Jan 6, 2026
- Heavy water is used as moderator in nuclear reactors
- Heavy water is more associated than ordinary water
- Heavy water is more effective solvent than ordinary water
- All of the above
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Heavy water, \( D_2O \), is used as a neutron moderator in nuclear reactors. It has a higher neutron absorption cross-section than regular water, making it more effective for slowing down neutrons. However, it is less common for other uses compared to ordinary water.
Step 2: Conclusion.
The correct statement is that heavy water is used as a moderator in nuclear reactors, corresponding to option (a).
Step 2: Conclusion.
The correct statement is that heavy water is used as a moderator in nuclear reactors, corresponding to option (a).
