cold water is much heavier than hot water . the water becomes warm
Its called water vapor.Its happens when the outside is really hot or warm and the inside of whatever is cool or cold.
It is hot because where the equator is, is a very how place.
This is what I read from another question, answered by ID0410848064: When hot lava meets the cooler temperatures of the ocean, an instantaneous cooling reaction takes place within the hot lava causing the minerals to form and crystallize quickly, usually of a different chemical and molecular composition if it were allowed to cool gradually at the earth's surface. Also, the hot lava may take on saline water from the ocean, therefore altering the overall mineral composition. Hope this helped :)
If the hot water tank is off it is possible. It is also possible for the cold water going to the hot water tank to freeze. Insulate all pipes that are exposed - or let them drip (this is more expensive!)
There are countless millions of chemicals that dissolve in hot water (or even in cold water). I don't know why you think there are only two. Water is a tremendously versatile solvent.
it melts.
Precipitation, usually in the form of rain, is a common reaction of a cold front when it meets a hot environment.
It evaporates. No matter if the water is cold, frozen, or even hot it evaporates.
A tornado forms
When hot water is thrown into cold air, the water quickly evaporates and turns into steam. This happens because the cold air causes the hot water to rapidly cool down, leading to a phase change from liquid to gas.
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.
When hot water is mixed with cold water, the overall temperature of the mixture will be between the initial temperatures of the hot and cold water. The hot water will transfer heat to the cold water, resulting in a gradual temperature equilibrium.
it makes warmth
you get warm water.
When hot water is poured into cold water, the hot water will transfer its heat energy to the cold water, causing the overall temperature of the mixture to increase. Eventually, the hot and cold water will reach a thermal equilibrium where they have the same temperature throughout the mixture.
Hot sugar is soft, when you add cold liquid it will get hard at once.
Hot and cold water can separate due to differences in their temperature and density. When hot and cold water are combined, the hot water tends to rise to the top because it is less dense than the colder water below. This process is known as thermal stratification.
