Question

question 1
describe the energy and motion of particles in a solid.

question 2
describe the energy and motion of particles in a liquid.

question 3
describe the energy and motion of particles in a gas.

Explanation:

QUESTION 1

In a solid, particles have low kinetic energy. They are closely packed in a regular arrangement and vibrate in fixed positions around their equilibrium points. The intermolecular forces are strong, restricting movement to vibrations.

In a liquid, particles have moderate kinetic energy. They are close together but not in a fixed arrangement. The intermolecular forces are weaker than in solids, allowing particles to slide past one another (flow) while still being relatively close.

In a gas, particles have high kinetic energy. They are far apart, and intermolecular forces are very weak. Particles move freely and randomly in all directions, with rapid, constant motion (including translational, rotational, and vibrational motion) and frequent collisions.

Answer:

Particles in a solid have low kinetic energy. They vibrate in fixed positions (due to strong intermolecular forces and a regular, close - packed structure).
