The air becomes cool and fresh.
the air pressure outside of the balloon decreases.
The tube will not contain lots of air
It gets thinner (the pressure drops) and colder.
The cold air.
As the airplane ascends to 30,000 feet, the air pressure outside the airplane decreases. This is because air pressure decreases with altitude due to less air molecules exerting pressure on the aircraft. The difference in pressure between the inside and outside of the airplane is managed by the aircraft's pressurization system to ensure a comfortable environment for passengers and crew.
This happens when the contents of the beaker are colder than the surrounding air. This causes water vapor in the warmer air to drop below its dew point and condense onto the outside of the beaker.
When the air inside the can is pumped out, there is a decrease in pressure inside the can. The outside air pressure then pushes on the sides of the can, causing it to collapse. This happens because the higher pressure outside the can is not balanced by the lower pressure inside the can.
Your house windows are fogging up on the outside due to condensation forming on the glass surface. This happens when the temperature of the glass is lower than the dew point of the air outside. To prevent this, you can improve ventilation around the windows, use a dehumidifier indoors, or install storm windows to create a barrier between the cold outside air and the warm indoor air.
The water and the air makes a chemical change to the nail to make it rust
the fresh air and the salty water
Most likely a cat settled over the hood vents and peed into the air con. Happens a lot when it's cold outside.
