Question

entropy is
a measure of the kinetic energy in the random movement of molecules.
a measure of the disorder or energy dispersal in a system.
a measure of the energy available for work in a thermodynamic system.
a measure of the energy stored in the chemical bonds of molecules.

Explanation:

Entropy is a fundamental concept in thermodynamics. It quantifies the degree of disorder or randomness in a system and also represents energy dispersal. Kinetic energy of random - molecular motion is related to temperature. The energy available for work is Gibbs free energy. The energy stored in chemical bonds is chemical energy.

Answer:

a measure of the disorder or energy dispersal in a system.
