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.

    The Pressure at the Bottom of a Container

    Homework Statement My physics textbook states that the pressure at some point in a fluid filled container a distance h below the fluid air interface is dependent only upon h, the density of the fluid, and the acceleration due to gravity. If this is the case, then the pressure at the bottom of...
