Container Definition and 347 Threads

A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping.
Things kept inside of a container are protected by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are usually at least partly rigid.
A container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials.

    Change of of the pressure of water inside a container

    I am having difficulty solving an exercise prepared by our professor for hydrodynamics. I am unsure if Laplace pressure is the correct way to calculate the pressure inside. It comes to my mind that I should've used the equation for hydrostatic pressure instead (##P=P_0+\rho gh##). However, the...

    Why did the lid of a heated container cave inwards?

    I microwaved a container of soup with a lid sitting on top. When I tried to remove the lid, a suction had formed and the lid was very difficult to remove, as if the volume and pressure of the container had both decreased. However, heated gas (in this case, steam from the soup) expands. So why...

    What is pressure when there are no container walls?

    Hi! I wonder what pressure is when there are no walls. The reason for me wondering this is that gas pressure actually is defined by change of particle momentum, like p=\frac{F}{S}=\frac{1}{S}\frac{dp}{dt}=\frac{1}{S}\frac{d2mv}{dt} So how can there be pressure without change of momentum...
