Question

Which factors decide whether a particular substance will be a solid, a liquid, or a gas?​

Answer 1

Two factors determine whether a substance is a solid, a liquid, or a gas:

1. The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance.

2. The attractive intermolecular forces between particles that tend to draw the particles together.

In this, both the given statements are correct.

Hence, option A is correct

Answer 2

Two factors determine whether a substance is a solid, a liquid, or a gas:

The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart.
The attractive intermolecular forces between particles that tend to draw the particles together.
If the average kinetic energy is greater than the attractive forces between the particles, a substance will not condense to form a liquid or a solid. If the kinetic energy is less than the attractive forces, a liquid or solid will form.
