Mention one change by force or pressure

Answers 1

Answer:

force can change the shape and size of the object .

force can change the speed of moving object.

Pressure creates no effect on solids or liquids because both these states of matter are non-compressible. But if pressure is increased on solid it breaks. But on the other hand application of pressure with reduced temperature can liquefy gases.

The biodegradable polymer is: | Chemistry Questions a.Nylon - 6,6 b.Nylon - 2 - Nylon 6 c.Nylon - 6 d.Buna - S

Answer:

What are Biodegradable Polymers? These are those polymers which get decomposed under aerobic or anaerobic conditions, as a result of the action of microorganism/enzymes. The materials develop it like starch, cellulose, and polyesters. Aliphatic polyesters are the most commonly used polymers of this type.

Explanation:

Hence, Nylon 2-nylon-6 is a biodegradable polymer. So, the correct answer is option B. Note: Buna-S is a synthetic rubber and nylon -6, nylon – 6, 6 is synthetic fibers. All of these polymers are prepared by condensation polymerization and non-biodegradable polymers.
