Hot water causes thermal expansion which leads to this issue and can easily be fixed by installing an expansion tank. (which is code in many areas) Also if your hot water heater is "turned" up to high or malfunctioning the water can boil and cause condensation within the system thus leading to air in the line.
All fresh water contains oxygen as water is heated it gives off bubbles like pot of boiling water
I think the only reasonable answer can be that the cold and hot water inlet/outlets are reversed. your hot water line is attached, at the heater to the cold water inlet or your hot water outlet is too short inside of the tank
The hot water heats the air in the system, causing it to expand.
Attach an auto air vent at the highest point on the line
Hot air with water vapours hit a old surface causing water droplets to form. If the hot air reaches a cold atmosphere, it's called precipitation aka rain.
Open hot water on a faucet. Air will come out instead of water until air is all out, then water should flow as normal. May need to install expansion tank to take care of excessive air pressure build-up in water line.
Because the heat from the hot water is transferred through the wall of the bottle to the inside, where it heats the air, causing it to expand and come out the top of the bottle.
The hot water heats up the air inside the bottle, causing it to expand, forcing some of the air out of the bottle and into the balloon, causing it to inflate. The larger the bottle, the more air that will be pushed into the balloon. The air in the balloon will quickly cool and, since hot air is less dense and therefore rises, the cooler air is forced back into the bottle to be heated up. Eventually the air will be a constant temperature and the balloon will reach the limit of inflation. As the water cools, the air cools and the balloon begins to deflate.
there are many possibilities. If you had your hot water heater replaced or fixed a water line then it could be air inside your water pipes and should go away after a while. you could have air still inside your water heater tank and when you first run hot water out of a fixture it could from flow bleed into your hot water pipe. If you think it isn't caused by air then your fixture can be the problem either your valve seal is loose or your aerator is bad. If you can find out either its air or water then it would easier to trouble shoot.
The Amazon is hot and humid due to its location. It is near the equator where the sun's rays are known to be more direct causing the immense heat. The humidity is contributed to the water in the air being heated. As the sun's rays are heating the Earth, the water in the air rises as well causing the humidity to rise in the Amazon.
Going up!Hot air is actually less dense than cold air. So, in turn the hot air rises causing the balloon to float up.Because hot air has a lower density than cold air, causing hot air to rise. When the hot air is trapped in a balloon, the push of the rising air causes the balloon to float.
They don't. Its the exhaust from the plane, and the hot air from the jets causing water to condense into clouds.
There are a few possibilities why. Troubleshoot asking yourself these questions: Is the hot water heater switched on electronically? Is the stop cock switched on? Are there air locks in the line? Is the hot water heater connected?
