The correct Answer is:
To solve the question regarding how water protects organisms from thermal shock, we can analyze the options provided: 1. **Understanding Thermal Shock**: Thermal shock refers to the rapid change in temperature that can be harmful to organisms. Water's properties play a crucial role in mitigating these temperature changes. 2. **Evaluating the Options**: - **(a) Thermal conductivity**: This refers to how well a substance can conduct heat. While water has a certain level of thermal conductivity, it is not the primary property that protects organisms from thermal shock. - **(b) Latent heat**: This is the amount of heat required to change the state of a substance without changing its temperature. Water has a high latent heat of vaporization, which means it can absorb a lot of heat before its temperature changes significantly. This property helps in maintaining a stable temperature in organisms. - **(c) Dielectric constant**: This is a measure of a substance's ability to insulate charges from each other. While water has a high dielectric constant, it is not directly related to thermal shock protection. - **(d) All the above**: This option suggests that all the properties listed contribute to thermal shock protection, which is not accurate based on our analysis. 3. **Conclusion**: The most relevant property that helps protect organisms from thermal shock is the high latent heat of water. This allows for slow heating and cooling, thus maintaining a stable internal temperature. **Final Answer**: (b) Latent heat ---
