The correct Answer is:
To determine which of the given statements is correct, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Analyze Statement A:** - The statement claims that the triple point of water is 253.16 K. - The triple point of water is actually defined as 273.16 K. - **Conclusion:** This statement is incorrect. 2. **Analyze Statement B:** - The statement claims that burns from steam are less severe than those from boiling water. - In reality, burns from steam are more severe than burns from boiling water because steam contains more energy (latent heat) than boiling water at the same temperature. - **Conclusion:** This statement is incorrect. 3. **Analyze Statement C:** - The statement claims that ethyl alcohol expands less than mercury for the same rise in temperature. - However, ethyl alcohol actually expands more than mercury for the same rise in temperature due to its higher coefficient of volume expansion. - **Conclusion:** This statement is incorrect. 4. **Analyze Statement D:** - The statement claims that when a fully inflated balloon is immersed in cold water, it will contract. - This is correct because the air inside the balloon will contract when cooled, leading to the balloon shrinking in size. - **Conclusion:** This statement is correct. ### Final Answer: The correct statement is **D**: When a fully inflated balloon is immersed in cold water, it will contract. ---
