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.
Rube Goldberg Process. By definition a Rube Goldberg machine is a machine that performs a very simple task in a very complicated and over-engineered manner. A chain reaction occurs where one element triggers the next element and so on, ultimately triggering the final element-the task of the machine.ube Goldberg Process.
