Why does cold water sink when poured OK into hot water?
When cold water is poured into hot water, it sinks because it is denser than the hot water. The cold water is heavier due to the molecules being closer together at a lower temperature, causing it to sink to the bottom. The hot water, which is less dense, rises to the top.
Why is the top of your refrigerator cold but not the bottom part?
The top of the refrigerator is cold because that's where the cooling unit is located, usually at the back. The cold air sinks, so it tends to stay at the bottom of the fridge where it keeps the food cool.
Are compressors supposed to be cold from top to bottom?
In general, compressors should be cooler at the top than at the bottom. This is because the cooling system typically starts at the top and moves downwards to prevent overheating. If a compressor is uniformly cold from top to bottom, it may indicate a cooling system issue or inefficient heat dissipation.
Why is the refrigerator cold at bottom and warm at top?
This temperature difference in a refrigerator is due to the way the cooling system is designed. Cold air sinks, so the bottom of the refrigerator, where the vents are usually located, is cooler. Meanwhile, the top shelves are warmer because they are farther away from the cooling source and are impacted by warm air that rises.
Why does the radiator get hot at the top but not the bottom?
The hot water that enters the radiator rises to the top as it is lighter and less dense than the cooler water at the bottom. This creates a temperature difference between the top and bottom of the radiator. Heat is transferred from the hot water to the radiator fins, which in turn heats the surrounding air.
All the downstairs radiators are cold on the bottom and hot on the top?
radiators are cold on the bottom and hot on the top?
My radiators in the bedrooms are cold and don't heat up but they are warm and toasty in the rest of the house we have oil heat any suggestions?
I assume that you are referring to hot water radiators, heated by an oil furnace. These radiators could have air in them and will not allow the hot water to fill them and give off any heat. If these are connected to the same hot water line that feeds the other working radiators, the in and out lines and the bottom on the cold ones should be hot. These radiators will then have to have the air bled out of them. They should have a valve on the top somewhere to do this. If there is no heat in the lines there must be separate line to that room that is plugged or shut off.
Why is the top of radiator hot and bottom is cold?
Warm gases and warm fluids rise to the top. Same principle that makes hot air balloons fly.
What type of water will things float down faster in warm or cold?
Cold will sink to the bottom. Hot water will rise to the top.
What insure that cold water is forced to the bottom of the water heater tank?
The cold water supply enters the tank at the bottom near the burner. Heat rises, as does hot water. The hot water supply is piped out from the top.
When to check oil level. when engine hot or cold?
On the dipstick there is a safe range. You can check it either hot or cold. When cold the level should be close to the bottom of the safe range. When hot it should be close to the top of the safe range.
What happens when the cold and hot water pipes are reversed on the hot water tank?
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.
Why Cold water is supplied to the bottom of hot water tank?
Cold water is supplied to the bottom of the hot water tank to prevent mixing of cold and hot water. This ensures that the hottest water is at the top of the tank where it can be drawn for use, while the cold water enters at the bottom to be heated by the heating element or burner. This also helps in creating a convection current within the tank for efficient heating.
What are some problems common with central heating systems?
Air may get trapped in a radiator, leaving it cold at the top whilst it is warm at the bottom. It then needs 'bleeding'. Radiators may also have the opposite problem, where they are warm at the top yet cold at the bottom. This is caused by a build up of sludge in the radiator and will probably require professional help. Sometimes the downstairs radiators stop heating up, whilst the upstairs ones are fine. This is caused by a problem with the pump and will again require professional help.
Why is the top of an oven hotter than the bottom?
Because - hot air is lighter than cold air - and thus it rises.
Why do hot water tanks have a heater fitted at the bottom rather than the top?
The reason for this is because hot water rises and cold water sinks. So as the heater heats the water the hot water rises to the top of the tank while the colder water sinks to the bottom to be heated. That is why the cold water inlet is installed at the bottom of the tank while the hot water outlet is on top.
Does hot and cold water mix with food coloring when hot water rises to the top?
Yes, hot and cold water can mix with food coloring when hot water rises to the top if there is sufficient turbulence or agitation to mix the colors together. The movement and flow of water can help distribute the food coloring throughout the container, allowing for mixing between different temperature layers.
