eli5: why does soap get more "soapy" in hot water and disappear in cold water?
gpt
Hot things have more energy. More energy means things tend to want to move more. The soap particles will disperse faster in the water because of this and when the soap is spread out, it's "soapy water".

It happens in cold water too, it's just that the soap is a bit more clumpy and not as evenly spread.
