Describe at least three ways in which condensation polymers differ from addition polymers in terms of their structures and the ways that they form.

Which of the following did you include in your response?

The monomers that form condensation polymers are di- or polyfunctional.

A polymer can grow from any location on the chain where a functional group is available.

A polymer does not contain all the atoms originally in the monomer units.

A small molecule, such as water, is produced when the monomers react to build the polymer.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

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.
