Which state of matter has the MOST energy?
Ierofanga [76]

The state of matter that has the most energy is gas. In a solid, there is limited room for molecules to move around.

The gas state of matter has the most energy because of how freely the molecules move. Matter is a physical substance of which there are three, and they are solid, liquid, and gas. Solid matter is very compact with the particles very close together and not much movement; therefore, no action, no energy.
