Question 1

1 mark

Which state of matter can be compressed (squeezed) into a much smaller space most easily?

Question 2

1 mark

On a humid day, you notice small droplets of water forming on the outside of a cold glass of soda. What is this process called?

Question 3

1 mark

A student fills Syringe A with \( 20\text{ cm}^3 \) of air and Syringe B with \( 20\text{ cm}^3 \) of water. After sealing the tips, the student pushes both plungers with the same force. The plunger in Syringe A moves significantly, while the plunger in Syringe B does not move. What does this demonstrate about the states of matter?

Question 4

1 mark

What happens to the shape and total volume of a wooden block when it is moved from a small box into a large plastic bowl?

Question 5

1 mark

If you blow air into a balloon, the balloon expands. What does this tell us about the volume of the air?

Question 6

2 marks

If you pour \(100\) ml of water from a tall glass into a wide bowl, does the total volume of the water change? Explain your answer.

Write your answer out first, then check it against the worked solution.

Question 7

3 marks

Compare boiling and evaporation. At what specific temperature does boiling usually occur for pure water at sea level?

Write your answer out first, then check it against the worked solution.

Question 8

5 marks

Gases are often described as being compressible. Using this property, explain why a juice box collapses inward when you suck the air out through a straw.

Write your answer out first, then check it against the worked solution.

Question 9

3 marks

A student uses three identical jars to study different states of matter.

Jar 1 contains a solid wooden block.
Jar 2 is filled with 100 ml of liquid water.
Jar 3 is filled with air (a gas).

(a) If the student moves the wooden block from Jar 1 into a much larger triangular box, what will happen to its shape?
(b) If the student pours the 100 ml of water from Jar 2 into a flat bowl, state whether its volume changes and explain why.
(c) Which jar contains a substance that can be easily compressed into a smaller space? Name the state of matter of that substance.

Write your answer out first, then check it against the worked solution.

Question 10

4 marks

A student is investigating the properties of different states of matter using two identical syringes. Syringe A is filled with 10 ml of water, and Syringe B is filled with 10 ml of air. The tip of each syringe is sealed tightly so nothing can escape.

(a) When the student tries to push the plunger of Syringe A, the plunger does not move. What property of liquids does this demonstrate?
(b) When the student pushes the plunger of Syringe B, the plunger moves inward easily. Explain this observation using the property of gases.
(c) If the 10 ml of water from Syringe A is poured into a wide glass bowl, what will happen to its volume and its shape?

Write your answer out first, then check it against the worked solution.
