Answer 1

There’s something called a refrigeration cycle. It’s a series of processes that you can do to a liquid or gas to make it cool something else. You can look up what it is later. For this cycle to be possible, certain properties are required. Refrigerants are the go-to materials today. If I recall correctly ammonia shows these properties, water doesnt.
