- MatterQuestionAnything that has mass and takes up space
- SolidQuestionMatter with a fixed shape and fixed volume
- LiquidQuestionMatter with a fixed volume that takes the shape of its container
- GasQuestionMatter with no fixed shape or volume; it spreads out to fill space
- PlasmaQuestionA hot, glowing state of matter made of charged particles
- Where is plasma found?QuestionIn stars, lightning and neon signs
- Bose-Einstein condensateQuestionA state of matter formed near absolute zero where atoms act as one
- Particles in a solidQuestionPacked close and only vibrate in place
- Particles in a liquidQuestionClose together but able to slide past each other
- Particles in a gasQuestionFar apart and moving fast in all directions
- MeltingQuestionSolid turns to liquid
- FreezingQuestionLiquid turns to solid
- EvaporationQuestionLiquid turns to gas at the surface
- BoilingQuestionLiquid turns to gas throughout, with bubbles
- CondensationQuestionGas turns to liquid
- SublimationQuestionSolid turns straight into gas
- DepositionQuestionGas turns straight into solid
- Melting point of waterQuestion0 degrees Celsius (32 degrees Fahrenheit)
- Boiling point of waterQuestion100 degrees Celsius (212 degrees Fahrenheit) at sea level
- Example of sublimationQuestionDry ice (solid carbon dioxide) turning into gas
- Example of depositionQuestionFrost forming on a cold window
- Is steam a gas or liquid droplets?QuestionInvisible steam is a gas; the white cloud you see is tiny liquid drops
- Does heating add or remove energy?QuestionIt adds energy, making particles move faster
- What happens to particles when matter cools?QuestionThey slow down
- Which state is the easiest to squeeze?QuestionGas
- Which state is almost impossible to squeeze?QuestionSolid and liquid
- Does a liquid have a definite volume?QuestionYes
- Does a gas have a definite volume?QuestionNo
- Is ice a solid, liquid or gas?QuestionSolid
- Is water vapor a solid, liquid or gas?QuestionGas
- Is air a solid, liquid or gas?QuestionA mixture of gases
- Is honey a solid or liquid?QuestionLiquid
- Is sand a solid?QuestionYes; each grain is a tiny solid
- Which is denser, ice or liquid water?QuestionLiquid water; ice floats
- Why does ice float?QuestionWater expands as it freezes, so ice is less dense
- ViscosityQuestionHow much a liquid resists flowing
- Surface tensionQuestionThe pull between liquid molecules that makes a skin at the surface
- CompressibilityQuestionHow much a material can be squeezed into less space
- VaporQuestionThe gas form of a substance that is usually a liquid or solid
- Freezing pointQuestionThe temperature at which a liquid becomes a solid
- Latent heatQuestionEnergy absorbed or released during a change of state without changing temperature
- Phase diagramQuestionA graph showing the state of a substance at different temperatures and pressures
- Absolute zeroQuestionThe lowest possible temperature, -273.15 degrees Celsius
- PressureQuestionForce pushing on a surface
- Kinetic theory of matterQuestionAll matter is made of tiny particles in constant motion
- DiffusionQuestionParticles spreading from where there are many to where there are few
- Which state of matter makes up most of the visible universe?QuestionPlasma
- Dry ice is made of what?QuestionFrozen carbon dioxide
- Is a cloud made of gas?QuestionIt is made of tiny liquid droplets or ice crystals in air
- Is toothpaste a solid or liquid?QuestionIt acts like both, a gel-like material
