ELI5: Why is hot water better at cleaning things than cold water?
gpt
Since high temperature will cause water molecules to move around relatively faster, it will also cause the hydrogen bonds between them to form and break at a higher rate (that is why hot water vaporizes more quickly than cold water). In addition, the high temperature increases the water's energy, and this energy may be used to break bonds between dirt and curtains for which colder water will not have enough energy.
