Which statement best describes plastics? a) plastics are large organic molecules called polymers b) plastics are large inorganic molecules the bond with silicone c) plastics are small organic molecules d) plastics are large inorganic molecules called polymers

Option (A) is the correct answer.

Explanation:

Plastics are basically organic polymers and it is known that polymers are long chain molecules.

Whereas when large number of monomer units combine together then it results in the formation of a polymer.

Plastics are able to change their shape and burn easily when come in contact of fire along with emission of harmful gases.

Therefore, we can conclude that the statement plastics are large organic molecules called Polymers, is true.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
