Q: Which of the following state of substance has the maximum kinetic energy?
  • A. Gas
  • B. Metalloid
  • C. Solid
  • D. Liquid
Correct Answer: Option A - The kinetic energy of particle is maximum in gaseous state. In gases particles are free to rotate with maximum speed as there is negligible force of attraction between the particles.
