The exhaust from car engines spreads throughout our atmosphere and adds to pollution. What is this an example of? A.

An increase in enthalpy

B.

An increase in thrust

C.

An increase in thermodynamics

D.

An increase in entropy

(D is the correct answer!)

When exhaust from car engines spreads throughout our atmosphere and adds to pollution then it is an example of increase in entropy.

Explanation:

A degree of randomness in the molecules of a substance is called entropy.

When exhaust from car engines spreads throughout our atmosphere then it means the molecules are moving at a faster speed due to which they spread into the atmosphere rapidly.

This means that the entropy of exhaust is increasing.

Thus, we can conclude that when exhaust from car engines spreads throughout our atmosphere and adds to pollution then it is an example of increase in entropy.
