Sample X has close, randomly arranged particles that move in curved paths past one another. Sample Y has particles fixed in rows that only vibrate. Which comparison is correct?
Sample X has particles far apart that move in long paths. Sample Y has particles fixed in close rows. Which statement correctly compares the samples?
Sample X has particles fixed in rows that only vibrate, sample Y has close particles that slide past one another, and sample Z has particles far apart that move in long paths. Which comparison is correct?
A sample keeps its own shape and volume when moved from a beaker to a watch glass; its particles only vibrate around fixed positions. Which state is it?
A sample has a definite volume but takes the shape of whatever container it is poured into. What state is the sample in?
A sample spreads out to fill an entire sealed flask and can be compressed easily. Which state is it?
Two different substances in the same state are placed next to each other with no stirring. In which state will they mix together fastest?
A substance forms a rigid crystal with particles arranged in a repeating pattern. Which state is described?
Which state of matter can flow but is very hard to compress?
A substance released at one side of a room eventually spreads throughout the room. Which state best matches that behavior?
Mercury melts at -39 °C. What state is a sample of mercury in at -50 °C?
In which state are the attractions between particles strong enough to keep them close together but too weak to hold them in fixed positions?
Oxygen melts at -219 °C and boils at -183 °C. What state is oxygen in at room temperature, 25 °C?
For most substances, which state has the highest density?
A sample settles to the bottom of a bottle, forms a surface, and keeps almost the same volume when transferred. Which state is it?
Water takes the shape of a flask when poured into it, but the amount of space the water occupies changes very little. Which particle model explains this?
A scent from an opened bottle can be smelled across the room after a few minutes. Which particle-level explanation fits?
A brick does not take the shape of the bucket it is placed in. What particle model explains this property?
Air in a bicycle tire can be squeezed into a smaller volume. Which particle-level reason best explains this?
Liquid mercury keeps nearly the same volume when poured into a shallow dish. Which explanation fits the particle model?
A small drop of water holds together on wax paper instead of instantly spreading into a thin film. Which particle idea helps explain this?
Smoke in a closed jar eventually spreads throughout the jar. Which explanation matches the particle model?
A thick liquid pours slowly but still changes shape to match its container. Which particle-level statement best explains this behavior?
During melting, energy is added to a solid. What happens to its particles on average?
When a liquid freezes, what particle-level change occurs?
A liquid absorbs energy and changes to a gas. Which particle-level change best describes vaporization?
Water vapor condenses on a cold glass. What happens to the particles as condensation occurs?
Dry ice changes directly from solid CO2 to CO2 gas at room pressure. What particle-level change happens as energy is absorbed?
Frost forms when water vapor changes directly into ice on a cold surface. What particle-level change occurs?
