Below are sample questions representative of the exercises included on this worksheet and related 4.15 States of Matter and Particle Model (Grade Appropriate) skill assessments:

Problem 1Difficulty: Mastery
A student fills an ice tray with liquid water, freezes it overnight, and then leaves the ice cubes in a bowl under a sunny window until the bowl is dry. Which answer best describes the full sequence?
Aliquid -> solid -> liquid -> gas because cooling then heating changed the state
Bliquid -> gas -> solid -> liquid because shape changed
Csolid -> liquid -> gas -> solid because sunlight adds cold
Dliquid -> solid -> gas because ice skips the liquid state in sunlight
Solution & Explanation:The water starts as a liquid, freezes into a solid, melts back into a liquid, and then evaporates into a gas as it dries.
Problem 2Difficulty: Mastery
Which explanation best connects what we see with the particle model when steam rises from soup?
AThe soup is burning away into nothing.
BSome liquid water particles gain enough energy to become gas particles that spread out in the air.
CAll particles become solids above the soup.
DSteam means the soup is no longer matter.
Solution & Explanation:Heating gives some water particles enough energy to leave the liquid as gas and spread through the air.
Problem 3Difficulty: Mastery
A student places an uncovered cup of hot water on a desk. Later there is less water in the cup. Another student holds a cold metal spoon above the cup and sees drops form on the spoon. Which explanation correctly describes both observations?
AWater froze in the cup and melted on the spoon.
BSome liquid water evaporated from the cup, and some vapor condensed on the cold spoon.
CThe spoon created water from metal.
DThe cup leaked into the spoon.
Solution & Explanation:Water left the cup by evaporation. When some of that water vapor touched the cold spoon, it condensed into liquid drops.
