Question:
Water acts as thermal buffer due to
Water acts as thermal buffer due to
Show Hint
Think about all the thermal properties of water, not only one.
Updated On: Nov 12, 2026
- high specific heat only.
- low heat of vaporization only.
- high heat of fusion only.
- high specific heat, high heat of vaporization and high heat of fusion.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
A thermal buffer resists sudden changes in temperature.
Step 2: Properties of water
High specific heat: water absorbs or releases a lot of heat with little temperature change.
High heat of vaporisation: evaporation causes strong cooling.
High heat of fusion: a lot of heat must be removed before water freezes.
Step 3: Conclusion
All three properties together make water a thermal buffer.
Final Answer:
Water acts as a thermal buffer because of its high specific heat, high heat of vaporisation and high heat of fusion. \[ \boxed{\text{(D) }\text{high specific heat, high heat of vaporization and high heat of fusion.}} \]
