Question

Of the 3 states of matter, solid, liquid, and gas, which has the lowest kinetic energy for a given substance?

Answer 1

The kinetic energy is the lowest at the solid state.

Explanation:

The kinetic energy (`K.E.`) is given by: `K.E.=3/2RT`.

Where, `R=8.3145J/(mol*K)` is the universal gas constant, and `T` is the temperature.

As could be seen from the expression of `K.E.`, since for the same matter, solid state exists at a lower temperature than liquid state and than gaseous state, therefore, the kinetic energy is the lowest at the solid state .
