Question

What is the measure of disorder in a system called? A. efficiency B. Enthalpy C. Work D. Entropy

Answer 1

D.) Entropy
Entropy is the measure of disorder in the universe.

Answer 2

Answer :  The correct option is, (D) Entropy

Explanation :

Entropy : It is defined as the measurement of randomness or disorderedness in a system.

The order of entropy will be,

As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.

As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.

Enthalpy : It is defined as the amount of heat added or removed from the system.

Work : It is the product of force and distance of an object.

Efficiency : It is defined as the percent ratio of output to input energy.

Hence, the measure of disorder in a system called entropy.
