Chemical refrigerants are assigned an R number which is determined systematically according to molecular structure.Common refrigerants are frequently referred to as Freon (a registered trademark of DuPont).hemical refrigerants are assigned an R number which is determined systematically according to molecular structure.
Some Rube Goldberg machines. use a complicated series of actions to simply move an object from. one place to another. Any object that is moving, has what is called kinetic energy; giving. an object more speed means giving it more kinetic energy.
Using the character, he would illustrate inventions that later become known as the âRube Goldberg Machineâ. A âRube Goldberg Machineâ is an extremely complicated device that executes a very simple task in a complex, indirect way.This is now used as an expression to describe any system that's confusing or complicated and came about from Goldberg's illustrations of absurd machines.he first illustration depicting a âRube Goldberg Machineâ was an Automatic Weight Reducing Machine in 1914 using components such as a donut, bomb, wax, balloon and hot stove to trap an obese person in a sound and food proof prison, who had to lose weight before wriggling free.
