Question

1. describe what you would see in a microscopic view of the particles in a solid, a liquid, a gas & plasma.

Explanation:

• Solid: Particles are closely packed in a regular, repeating pattern (lattice structure). They vibrate in fixed positions, have strong intermolecular forces, and maintain a definite shape and volume.
• Liquid: Particles are close together but not in a fixed arrangement. They can slide past one another (flow), have moderate intermolecular forces, and take the shape of their container while maintaining a definite volume.
• Gas: Particles are far apart and move freely in random directions at high speeds. They have weak intermolecular forces, fill the entire volume of their container, and have no definite shape or volume.
• Plasma: It is an ionized gas with free - moving charged particles (ions and electrons). Particles are highly energetic, move very rapidly, and the system is affected by electric and magnetic fields. Plasma often emits light (e.g., stars, neon signs) and does not have a definite shape or volume.

Answer:

• Solid: Particles are closely packed in a regular lattice, vibrating in fixed positions.
• Liquid: Particles are close, slide past each other, taking container's shape (definite volume).
• Gas: Particles are far apart, move randomly at high speeds (no definite shape/volume).
• Plasma: Ionized gas with charged particles, highly energetic, affected by fields, emits light (no definite shape/volume).
