yes
no they will melt if it is hot enough
the pressure difference, depends upon the can, and what it contains, in food cans, the pressure is equil, however in soda pop cans the pressure is higher on the inside
Because the air pressure INSIDE the can is the same as the air pressure OUTSIDE the can !
Aluminum is the flexible and pliable material most cans are made from, making them easy to crush.
Equal pressure inside us.
Yes it can. Depending on the range of air pressure between earth and space
because the air has pressure so when we crush the air is expand
The air pressure is the same inside as outside the can.
There is air pressure on all sides, inside or outside. The air pressure pushes on the object all ways and nothing falls. If you only apply pressure on the bottom then the object will lift. If you apply pressure on the top, the object will collapse. If air pressure is pushing side ways, the object will move sideways.
It compresses the air in or around it making it crush into itself because the air around it is being compressed so tightly togetherit has to make room for itself.
Every day objects are surrounded by air, on all sides and inside, so all the force of the weight of the air acts equally in all directions.
Air pressure WILL crush objects. A standard experiment is to fill a 1 gallon can with water, and then closely fit a small diameter hose to the outlet. Invert the can, and if your hose was indeed sufficiently small, the water will drain out, and the can will collapse due to the air pressure from outside overcoming the strength of the can walls. Air pressure will not crush solid objects in general for they are already as dense as they can become.
