Question

If someone was to say “order will always become disorder”, how would you explain to them that you could put order back?

Answer 1

Answer:

•B. a form of energy is required to be input so it can become orderly again

Explanation:

Order can be restored from a disordered system by inputing energy. The energy helps restore back the orderliness in a system.

We know that entropy is the state of randomness or disorderliness of the particles of a system. Entropy increases with rise in temperature. When the heat energy that causes temperature rise is removed from a system, the kinetic energy require for molecules to move is reduced and orderliness can gradually be approached.

For example, heating of water causes agitation of its molecules. The randomness of it particles increases. This is seen in the phase change from liquid to gases. As temperature is lowered, the water cools and orderliness is approached again. We can approach more orderliness by putting the water in a refrigerator.

In some systems, we can bring gases into a more ordered state by compression. The pressure applied to compress gases is a form of energy because work is done to bring the molecules into close contact as seen in a gas cylinder.
