Question

Which of the following statements regarding entropy is false?

a. Crude oil refined to make gasoline. The entropy of the crude oil incrases

b. A rock falls to strike the ground. The entropy of the rock and ground increases

c. A layer of a salt then a lyer of peppe are plaed in a jar then shaken. The entropy of the salt and pepper increases.

d. A log in a fire burns to form ashes. The entropy of the log increases.

Answer 1

option A is correct here.

because we know that entropy is the measurement of randomness.

As from crude oil to gasoline , crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, and liquefied petroleum gas.

This indicates that crude oil have many components in it make its entropy higher and when it is refined, its entropy decreases in each phase like gasoline etc.

Hope this helped.
