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.

    Potential Energy of Rising Water Container

    A container with a hole in the bottom is filled with water. As the container is raised, water flows through the hole; thus the mass of the water in the container decreases. What is total potential energy of the water and water container over a specific time period as water escapes the container...

    Why Decreasing Container Volume Doesn't Increase Temperature?

    I understand that as temperature increases the volume of the container will also rise. Due to the particles having more KE and coming in contact with the container walls more frequently and with more force. My question is.. why isn't the inverse true? When you decrease the volume of the...
