What do the states at room temperature and the melting points tell you about the strengths of the forces between the particles for each of the three substances?

Answer:

The state of a substance at room temperature can give an indication of the strength of the forces between its particles. If a substance is a solid at room temperature, it suggests that the forces between its particles are strong enough to hold them in a fixed position. If it's a liquid, the forces are weaker, allowing particles to move past each other, but still strong enough to keep them close together. If it's a gas, the forces are very weak, allowing particles to move freely and far apart from each other.

The melting point of a substance also provides information about the strength of the forces between its particles. A high melting point indicates strong forces, as a lot of energy is needed to break them and turn the substance from a solid into a liquid. Conversely, a low melting point suggests weaker forces.

For example, if Substance A is a gas at room temperature and has a low melting point, Substance B is a liquid at room temperature and has a medium melting point, and Substance C is a solid at room temperature and has a high melting point, we can infer that Substance C has the strongest forces between its particles, followed by Substance B, and then Substance A with the weakest forces.
