With that, a sophisticated crushing design can prevent an unwanted rise in temperature, fire, chemical reactions, or explosions [68, 69]. However, the process medium influences also the process design and process control (i.e., continuous or discontinuous operation) and the overall operating and technological costs.

The dimensions of the cans are also designed specially in order to withstand the outside pressures. A square inch of a soda can bears 80-90 pounds of force from outside. One atmosphere pressure force is equals to 720lbs or 3200newtons. So, in order to crush a soda can, you need to give nearly 50 pounds of force.

Acting upon matter can cause it to change, but it is useful to separate these changes into two different categories: physical and chemical. A chemical change describes a process that changes one material into another. Burning wood causes it to turn into ash, a different material. A physical change is simply changing the shape or state, such as cutting a …

7.0: Prelude to Energy and Chemical Processes. Metabolism is the collective term for the chemical reactions that occur in cells and provide energy to keep cells alive. Some of the energy from metabolism is in the form of heat, and some animals use this heat to regulate their body temperatures. Such warm-blooded animals are called endotherms.
