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.
1 Electrical Energy is when electricity creates motion, light or heat. 2  An example of electrical energy is the electric coils on your stove. 3  Gravitational Energy is motion that is caused by gravity. 4  An example of gravitational energy is water flowing down a waterfall.
