Which state of matter has the highest entropy

Answer: gaseous state

Entropy is the measure of the disorder of a system and is a function of state. That is, it depends only on the state of the system.

In this sense, in the gaseous state is where the greatest entropy occurs, since in a gas the particles acquire greater freedom and kinetic energy to move.

Another aspect that influences the increase in entropy is the increase in temperature. This is because, when raising the temperature, the kinetic energy of the molecules, atoms or ions increases, and, therefore, they move more.
