Question

Which state of matter solid,liquid,or gas have the heighest internal energy?

Answer 1

Gas

Explanation:

Internal energy is basically the distribution of the TOTAL kinetic energy of all the molecules. In the gaseous state, molecules are free to move and move randomly and fast everywhere around in space. That means that they have the most kinetic energy. Technically however, in the state of plasma molecules would have the highest internal energy, but here, we are only given the choices of solid, liquid, and gas, so gas would be the correct answer.
