states of matter quiz

📚 Quick Study Guide

• 🧊 Solid: Has a fixed shape and volume. Particles are tightly packed and vibrate in place.
• 💧 Liquid: Has a fixed volume but takes the shape of its container. Particles are close together but can move around.
• 💨 Gas: Has no fixed shape or volume. Particles are widely separated and move randomly.
• 🔥 Plasma: An ionized gas that is very hot and carries an electrical charge. Often considered the fourth state of matter.
• 🌡️ Melting: The change from solid to liquid. The temperature at which melting occurs is called the melting point.
• 🥶 Freezing: The change from liquid to solid. The temperature at which freezing occurs is called the freezing point.
• ♨️ Boiling/Evaporation: The change from liquid to gas. Boiling occurs at a specific temperature (boiling point), while evaporation can occur at any temperature.
• 🌬️ Condensation: The change from gas to liquid.
• 🧊 Sublimation: The change from solid directly to gas (e.g., dry ice).
• 🧊 Deposition: The change from gas directly to solid (e.g., frost formation).
• 🔢 Formulas:
  • Density: $\rho = \frac{m}{V}$ (where $\rho$ is density, $m$ is mass, and $V$ is volume)
