Which of the following is a measure of randomness in a system?potential energychemical energycalorieentropy

Identifying the Measure of Randomness

1. Potential Energy: This is the stored energy in a system due to position or configuration. It does not directly relate to randomness.

2. Chemical Energy: This refers to the energy stored in the bonds of chemical compounds. Like potential energy, it does not indicate randomness.

3. Calorie: This is a unit of measure for energy, particularly in relation to heat. While it can reflect energy changes, it does not measure randomness.

4. Entropy: This is a fundamental concept in thermodynamics and statistical mechanics, which quantifies the level of disorder or randomness in a system. Higher entropy means greater disorder and randomness.

Final Answer

The measure of randomness in a system is entropy.
