huntagain2008 “水在 4°C 时体积最大吗？” 我用 gpt4 是这样回答的： “是的，在 4℃时，水的密度达到最大，体积相对最小”；
“假设水在 60 华氏度冰冻，以及这将如何影响地球” (prompt：”Assuming water freezes at 60 degrees Fahrenheit, and how that would affect the planet“)
gpt4 是这样回答的：
“If water were to freeze at 60 degrees Fahrenheit (15.56 degrees Celsius), it would have a significant impact on the Earth's climate, ecosystems, and human society. Here are some of the consequences of such a change:
1. Climate: The increase in the freezing point of water would alter the Earth's climate dramatically. Regions that currently have temperate climates would become much colder, with a significant portion of their precipitation falling as snow, rather than rain. This would lead to longer, colder winters and shorter, cooler summers.
2. Ocean currents: The altered thermal properties of water would likely affect ocean currents. The thermohaline circulation, driven by differences in temperature and salt concentration, would be impacted, disrupting the transport of heat around the planet. This could lead to more extreme weather patterns and a further cooling of already cold regions, such as the poles.
3. Ice cover: With an increased freezing point, ice would be more prevalent on Earth. The polar ice caps would expand, potentially causing sea levels to drop. The growth of ice in mountainous regions would further change local climates and ecosystems.
4. Ecosystems: The change in climate and increase in ice cover would have dire consequences for ecosystems around the world. Many plants and animals would face extinction”
