Greatest significance of latent heat:
Explanation:
- Latent heat: Latent heat is the energy absorbed or released by a substance during a phase change without a change in temperature.
- Significance of latent heat:
- Allows water vapor to serve as a large reservoir of heat in the Earth's atmosphere: Water has a high latent heat of vaporization, meaning it requires a large amount of energy to change from liquid to vapor. This allows water vapor to absorb and store a significant amount of heat energy in the Earth's atmosphere, contributing to the regulation of global temperatures and climate.
Conclusion: The greatest significance of latent heat is that it allows water vapor to serve as a large reservoir of heat in the Earth's atmosphere, contributing to the regulation of global temperatures and climate.

Understanding Latent Heat
Latent heat is an essential concept in thermodynamics, particularly significant in the context of water and its role in Earth's climate system.
What is Latent Heat?
- Latent heat refers to the energy absorbed or released by a substance during a phase change, such as from liquid to gas or vice versa, without changing its temperature.
Why is Option B Correct?
- Water Vapour as a Heat Reservoir:
- Water vapour plays a crucial role in the atmosphere, acting as a major reservoir of heat.
- When water evaporates, it absorbs heat from the surroundings, which helps cool the environment.
- When water vapour condenses back into liquid, it releases this stored heat into the atmosphere, warming the air.
- Climate Regulation:
- This process is vital for maintaining climate and weather patterns.
- The release of latent heat during condensation contributes to the formation of clouds and precipitation, impacting weather systems globally.
Other Options Explained
- Option A and D mistakenly suggest that the release of latent heat breaks down hydrogen bonds, which is not accurate. Instead, latent heat is involved in the formation and breaking of these bonds during phase changes.
- Option C focuses on glacial ice and its melting but does not emphasize the broader role of latent heat in regulating atmospheric temperatures and contributing to weather systems.
Conclusion
In summary, the greatest significance of latent heat lies in its ability to allow water vapour to serve as a large reservoir of heat in the Earth’s atmosphere, influencing climate and weather dynamics.
