– why can water taps provide very hot water but not very cold water

Question

We can turn our taps to easily provide us with hot water when doing the dishes, but if we want a cold cup of water we need to add ice – why?

Answer 1

Heating water and cooling water require different processes. Most buildings only have a water heater, and the “cold” water is really just the ambient temperature of the water sitting in the tank/pipes. It’s totally possible to make water colder, but it’s expensive and not usually worth all that fuss/infrastructure when you can just add some ice.
