Hot water is lighter then cold water so it would stay up on top of cold water till both waters naturalize to the same temp. a good example is a water heater and (if its not to old) open your drain at the bottom of the water heater and if your dip tube is still good you should always get cold water out of it even if the water heater is on and your water heater pressure is on.
If you have the hot water and pour the cold water on top of the closed container. I believe that just lowers the air pressure inside of the container, allowing the hot water to boil at a lower temperature.
For the water to reach the boiling point you must add heat to it. If it is hot to start with it needs less heat added .
water boils because heat has it it and water is easy to get boiled
hot water floats above cold water because it is less dense than cold water making molecules spread apart therefore making it float. scrw that answer because hot water has less mass and weight
Because everyone likes to take baths with hot water and all hot water is made out of is cold because all they do is boil hot water.
The density of cold water is higher that hot water
It is because cold water is more dense than hot water, thus hot water floats on cold water
I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.
well the water in the syringe will evaporate and you will see condensation at the top of the syringe.
in a pot on the stove, cold water sinks to the bottom and hot water circulates on the top of the pot. (The colder water needs to become hot, so it sinks to the bottom. That's why you see movement in the pot of water.)
If the dip tube (cold) side is broken or disintegrated. The dip tube is a long tube that forces cold water to the bottom of the water heater so that it keeps the hot water at the top and the cold water from mixing with the hot water. The dip tubes for most maufacturers are made by one company and are made of plastic. There was a oxidizing problem with the tubes in the late 80's and thru the 90's. Oxygen deteriorated the tubes and they disintigrated. Therefore the hot water and the cold water mixed at the top and you get only luk warm water after a short period. Also check that you have 220 volts at the thermostats on the water heater and that the circuit or circuit breaker are not broken going to the water heater.
My answer is, that there are air bubbles in the bottom of it, (WHEN ITS BOILING) Than those air bubbles rise to the top, & That's how hot water bubbles more than cold water.
It depends on the situation. If cold and hot water were mixed roughly together, they will simply mix with each other. However, when hot water is poured over cold water gradually, they will not mix and the hot water will remain on top of the cold water. This always happens when using a large container. In a small container, they will also mix immediately.
I think not because cold water is heaver than hot water and hot water rises to the top and cold drops to the bottom.
You will get warm instead of hot water. There is a tube inside the tank on the cold side that goes to the bottom of the tank and the hot comes directly from the top. Reverse them and you are going to get the cold water that settles to the bottom of the tank. It will not hurt the tank or anything, it just makes for poor hot water.
Yes
Cold water is denser then hot water and weighs more so hot water will always stay on top of cold water no matter the pressure in the line or volume unless forced by flow hot water water will always be on top.
Flour to cold water will just float on top, hot water to flour will cook the flour.
There is no such thing as hot ice. The ice is a cold and frozen solid made out of water. Ice happens when water freezes at 0 degrees Celsius. But if the ice is hot, it will turn into water. If you touch the top of fridge it most of the time hot or at room temperature, so the water(hot ice as you said it) will remain at the same temperature as the room or hot.
The question doesn't contain enough information. When you open the hot water facet, does the water come out hot, but cools quickly? If so then you probably need to replace the dip tube. The dip tube insures that the cold water is injected at the bottom of the tank as the hot water is with drawn from the top of the tank. Dip tubes are mounted in the cold water input side at the top of the tank. some times dip tubes break off at the top so when you start drawing hot water from the top of the tank the cold water is injected into the top of the tank and this makes your hot water cool quickly. The water will come out hot, but will cool quickly. Normally when the cold water is injected into the bottom of the tank (through the dip tube) it will displace the entire tank full/column of hot water out through the top of the tank before the cold water gets to the top.
Yes, as hot water is less dense than cold water so it will float on top of cold water. Over time the temperatures will equalise due to natural conduction and convection.
it puts cold water in and pushes hot water to the top

Cold will sink to the bottom. Hot water will rise to the top.
