The noise that the plane makes is sometimes so loud that you cannot hear any other noise. Sound is a type of energy. Sounds are produced when an object vibrates. When this happens, the air around the object also vibrates. These vibrations in the air travel as sound waves. A jet engine makes a great deal of sound energy. The engine sounds loud when it is close, but you can sometimes hear the noise when the plane is even several miles away from you.
Definition of Polymer. A large molecule consisting of chains or rings of linked monomer units, usually characterized by high melting and boiling points.
Making the world better, one answer at a time. A polymer (a chemical term) is any material that is made up of repeating linked units (monomers). An example of a polymer is starch. It is made from linked units of Glucose (a sugar).Another example is plastics such as low density polyethylene made from linking repeating ethylene (a gas) units. Maybe a more familar example that is used around the house is when you repair your car with fiberglass.aking the world better, one answer at a time.
