This challenging worksheet has students answer multiple-choice questions, and fill in blanks to practice properties of matter skills.
It includes 9 questions across 2 sections for focused practice.

Part A: Multiple Choice
Circle the best answer for each question.
1. A student stirs sugar into cold water until no more dissolves. She then heats the water and adds more sugar, which dissolves. What conclusion is best supported?
A) Heating water creates a chemical reaction that breaks down the sugar molecules.
B) Increasing the temperature of the solvent allows more solute to dissolve.
C) The sugar melted from the heat rather than actually dissolving in the water.
D) Cold water cannot dissolve any sugar, so all the sugar settled on the bottom.
2. A pot of boiling water is left on the stove for a long time and the water level drops. Where did the water go?
A) The water was destroyed by the heat energy from the stove burner.
B) The water molecules changed into oxygen and hydrogen gas permanently.
C) The water evaporated and entered the air as invisible water vapor.
D) The water was absorbed into the metal of the pot through tiny holes.
3. A glass of ice water is left on a table and water droplets form on the outside of the glass. What caused this?
A) Water leaked through microscopic cracks in the glass wall.
B) The cold glass caused water vapor in the surrounding air to condense on its surface.
C) The ice inside the glass pushed liquid water through the glass by pressure.
D) Warm air heated the glass and made it sweat like a person exercising.
4. A student wants to dissolve a sugar cube faster without changing the temperature of the water. Which strategy would work best?
A) Use a larger container so the water has more room to react with the sugar.
B) Add more sugar cubes so they help each other dissolve more quickly.
C) Crush the sugar cube into powder to increase the surface area touching the water.
D) Let the sugar sit longer without stirring because time alone speeds dissolving.
Part B: Fill in the Blank
Write the correct answer on each line.
1. The ability of a substance to dissolve in another substance is called its solubility.
2. During freezing, a liquid loses thermal energy and its particles slow down enough to form a solid.
3. Crushing a solute into smaller pieces helps it dissolve faster by increasing its surface area.
4. Water droplets forming on a cold glass is an example of condensation, where gas turns to liquid.
5. During boiling, the vapor pressure of the liquid equals the air pressure pushing down on its surface.
