States of Matter Quiz

Solid State

• Particles are closely packed and have a fixed position
• Vibration occurs, but no change in position
• Has a fixed shape and volume
• Examples: rocks, metals, ice

Liquid State

• Particles are close together but are free to move past each other
• Particles have some kinetic energy, but are still attracted to each other
• Takes the shape of its container and has a fixed volume
• Examples: water, oil, juice

Gas State

• Particles are widely spaced and are free to move randomly
• Particles have high kinetic energy and are not strongly attracted to each other
• Has neither a fixed shape nor a fixed volume
• Examples: air, helium, oxygen

Plasma State

• Particles are ionized, meaning they have lost or gained electrons
• Particles are highly energetic and move freely
• Has neither a fixed shape nor a fixed volume
• Examples: lightning, neon signs, stars

Changes of State

• Melting: solid to liquid (absorption of heat)
• Freezing: liquid to solid (release of heat)
• Vaporization: liquid to gas (absorption of heat)
• Condensation: gas to liquid (release of heat)
• Sublimation: solid to gas (absorption of heat)
• Deposition: gas to solid (release of heat)

Factors Affecting State Changes

• Temperature: increases in temperature favor transitions to higher energy states (e.g., solid to liquid)
• Pressure: increases in pressure favor transitions to lower energy states (e.g., gas to liquid)
• Surface area: increases in surface area favor transitions to higher energy states (e.g., solid to gas)

Solid State

• Particles are closely packed and have a fixed position, resulting in a rigid structure
• Although particles vibrate, they do not change position, maintaining a fixed shape and volume
• Examples of solid states include rocks, metals, and ice

Liquid State

• Particles are close together but are free to move past each other, allowing for fluidity
• Particles have some kinetic energy, but are still attracted to each other, maintaining a fixed volume
• Liquids take the shape of their container, with examples including water, oil, and juice

Gas State

• Particles are widely spaced and are free to move randomly, resulting in a state of high kinetic energy
• Particles have weak intermolecular attractions, allowing for expansion and contraction
• Gases have neither a fixed shape nor a fixed volume, with examples including air, helium, and oxygen

Plasma State

• Particles are ionized, meaning they have lost or gained electrons, resulting in highly energetic and freely moving particles
• Plasmas have neither a fixed shape nor a fixed volume, with examples including lightning, neon signs, and stars

Changes of State

• Melting occurs when a solid absorbs heat and transitions to a liquid
• Freezing occurs when a liquid releases heat and transitions to a solid
• Vaporization occurs when a liquid absorbs heat and transitions to a gas
• Condensation occurs when a gas releases heat and transitions to a liquid
• Sublimation occurs when a solid absorbs heat and transitions directly to a gas
• Deposition occurs when a gas releases heat and transitions directly to a solid

Factors Affecting State Changes

• Temperature increases can induce transitions to higher energy states, such as solid to liquid or liquid to gas
• Pressure increases can induce transitions to lower energy states, such as gas to liquid or liquid to solid
• Surface area increases can facilitate transitions to higher energy states, such as solid to gas or liquid to gas
