Question

1. define matter and describe the different states of matter.
2. compare the particle arrangement and energy in solids, liquids, gases, and plasma.

Explanation:

• Matter: Matter is anything that has mass and occupies space. It is composed of atoms and molecules.
• States of Matter:
• Solid: Particles are closely packed in a fixed, orderly arrangement. They have low energy and vibrate in place. Solids have a definite shape and volume.
• Liquid: Particles are close but can move past one another. They have more energy than solids. Liquids have a definite volume but take the shape of their container.
• Gas: Particles are far apart and move freely. They have high energy. Gases have no definite shape or volume; they fill the entire container.
• Plasma: Similar to gas but consists of charged particles (ions and electrons). It has very high energy. Plasma is often found in stars and in some high - energy laboratory settings.
• Particle Arrangement and Energy Comparison:
• Solid: Tightly packed, low - energy particles.
• Liquid: Less tightly packed than solids, moderate energy.
• Gas: Loosely packed, high - energy particles.
• Plasma: Charged particles, extremely high energy (higher than gas in terms of particle kinetic and potential energy due to ionization).

Answer:

• Matter is defined as anything with mass and space - occupying. States: solid (fixed shape/volume, low - energy, ordered particles), liquid (definite volume, takes container shape, moderate - energy, mobile particles), gas (no definite shape/volume, high - energy, free - moving particles), plasma (charged particles, very high - energy).
• Particle arrangement: solid (tight, ordered) < liquid (less tight) < gas (loose) < plasma (charged, loose). Energy: solid (low) < liquid (moderate) < gas (high) < plasma (very high).
