If you let hot water cool down, it will become cold water.
Given an identical volume of both to begin with (say, one gallon hot water, and one gallon cold water) they will be identical in weight. However, cold water is more dense than hot water.
Water can be either hot or cold depending on the temperature. Water at room temperature is considered neither hot nor cold.
There is one bowl of hot water and one bowl of cold water and one bowl of warm water. You place one hand in the hot and one hand in the cold for approx. 30 seconds and then place your hands in the warm water and that hand that was in the hot water will feel cold and the hand that was in the cold water will feel hot. This is because the nerves have gotten used to the temperature and therefore have to adjust again to return to normal. Thanks! That helps a lot! I knew I had done it before but I couldn't remember what it was!
Hot water is less dense than cold water. So if you have equal volumes of both,then the cold one is heavier than the hot one.* That's why we build stoves in such a way as to heat the bottom of the pot ...that's where the colder liquid is.
When hot water and cold water are mixed together, heat flows from hot water to cold water and brings them to equilibrium at a temperature intermediate to that of hot water and the cold water That may be right, but I think that the hot water would be more dominant causing the cold water to almost instantly turn hot.
HOT rises COLD sinks

Hot water is less denser than cold water and has a greater temperature.

Tepid water is between hot and cold.
Try shaving in cold water -you'll see one of them.
No, cold water is piped into the hot water tank and is heated by electricity or gas, it then flows out to the hot water taps.
