Assuming you mean the cooling system overflow.
If so:
* A worn or damaged coolant cap can cause coolant release long before the engine heats up. * an overfilled cooling system will release coolant when the engine warms. * If an engine overheats, either from low coolant, damaged or plugged radiator or worn out or damaged water pump or thermostat, the heat from the engine will turn remaining coolant to steam, creating quite a bit of pressure. * Once an engine has overheated it is possible that the head or block have been damaged. Damage can be either a warped head or as severe as a cracked head or block. You need to determine WHICH has caused the excessive pressure.
As the plane climbs, the pressure drops, even in a pressure cabin. The pop is your ears equalizing from ground pressure to altitude pressure.
the pressure inside the pot will build up and pop the lid off
Because it is under pressure.
Hey sexy it will get flatened and when the pressure is taken off it will pop back up. Bye babes
they will usually overflow, but in some cases they will pop.
Just pull it up with a good deal of pressure and it will pop off and dont worry it will pop right back on.
This also frequently occurs on landing mainly because of the difference in air pressure.
Ears "pop" when there is a change in pressure. It is the bodys way to prevent discomfort from pressure changes.
In order to keep the pop carbonated (fizzy), there must be air pressure built up in the can. The pop or whoosh you hear when opening a can is that air pressure escaping.
Yes there should be a overflow vent in the overflow reservoir. Think about it this why, if it was not there and pointing downward. If during a overheat period the lid were to pop off. The result would be a hot water volcano. Trust me you don't want that. Good Luck and Remember.Change Your Mind, Not Your Oil.Use the First In Synthetic Motor Oil's.See My Bio For more information.
A can of Pop Pops when you open it because the pressure in the can is released from the can when it's opened.
Use hot glue gun to build it
