The diagram below shows the change of states of a substance. The different processes are represented by A, B, C, and D. Which one of the following correctly represents A, B, C, and D?
- A.
Freezing, Condensation, Melting, Boiling
- B.
Boiling, Freezing, Condensation, Melting
- C.
Melting, Boiling, Condensation, Freezing
- D.
Condensation, Melting, Boiling, Freezing
Correct Answer
C. Melting, Boiling, Condensation, FreezingExplanation
The diagram shows the change of states of a substance. The process represented by A is melting, where the substance changes from a solid to a liquid. The process represented by B is boiling, where the substance changes from a liquid to a gas. The process represented by C is condensation, where the substance changes from a gas to a liquid. The process represented by D is freezing, where the substance changes from a liquid to a solid. Therefore, the correct representation is Melting, Boiling, Condensation, Freezing.Rate this question:

A kettle containing some tap water was heated until it boiled. White clouds were seen coming out of the spout. A metal tray was placed above the spout of the kettle. Which of the following statement about the experiment is not correct?
- A.
The white clouds were made up of tiny water droplets
- B.
The tap water gained heat and turned into gaseous state which were the white clouds.
- C.
The metal tray became warm eventually and fewer water droplets were formed on the tray
- D.
The hot water vapour from the spout touched the cooler surface of the metal tray, lost heat and condensed into water droplets
Correct Answer
B. The tap water gained heat and turned into gaseous state which were the white clouds.Explanation
The correct answer is that the tap water gained heat and turned into a gaseous state which were the white clouds. This statement is not correct because the white clouds were actually formed when the hot water vapor from the spout touched the cooler surface of the metal tray, lost heat, and condensed into water droplets.Rate this question:

The table below shows the melting points of substances W, X, Y, and Z. Which of the substance(s) will be in the liquid state at 35oC?
- A.
W only
- B.
W and X only
- C.
X and Z only
- D.
X, Y, and Z only
Correct Answer
C. X and Z onlyExplanation
The substances that will be in the liquid state at 35oC are X and Z only. This is because their melting points are below 35oC, indicating that they will be in the liquid state at this temperature. Substance W has a higher melting point, so it will be in the solid state at 35oC. Substance Y is not mentioned in the answer choices, so we cannot determine its state at 35oC.Rate this question:

Three glasses A, B, and C were filled with the same amount of water. the temperature of the water is different in each glass. After 15 minutes, water droplets were seen on B and C as shown below. no water droplets were seen on A. Which one of the following correctly shows the arrangement of the glasses based on the temperature of water it holds? (highest water temperature --> lowest water temperature)
- A.
A --> B --> C
- B.
B --> A --> C
- C.
C --> A --> B
- D.
C --> B --> A
Correct Answer
C. C --> A --> B -

Two metal containers, K and M, each contained 200 cm3 of water. Jim recorded the volumes of water in containers K and M every hour. Which of the following is the correct graph for these results?
- A.
Option 1
- B.
Option 2
- C.
Option 3
- D.
Option 4
Correct Answer
B. Option 2Explanation
The correct graph for the results would show a constant volume of water in both containers over time. Option 2 is the only graph that shows a straight line at the same level, indicating that the volume of water in both containers remains constant. Option 1 shows a decreasing volume in container M, Option 3 shows an increasing volume in container K, and Option 4 shows a decreasing volume in both containers.Rate this question:

The diagram below represents the water cycle. At which stage(s) is/are heat gained by water?
- A.
X only
- B.
Y only
- C.
Z only
- D.
W and Y
Correct Answer
B. Y onlyExplanation
Stage Y represents the process of evaporation, where water changes from a liquid to a gas due to the input of heat energy. This means that heat is gained by water during stage Y. The other stages (X, Z, and W) do not involve the input of heat energy to water.Rate this question:

The graph below shows how the temperature of water in a beaker changes when heated over time. Which line in the graph shows the boiling point of water?
- A.
AB
- B.
BC
- C.
CD
- D.
BD
Correct Answer
C. CDExplanation
The line CD shows the boiling point of water because it is the point where the temperature of water starts to rapidly increase and reaches its highest point. This indicates that the water is transitioning from a liquid state to a gaseous state, which is the boiling point of water.Rate this question:

Two identical cups, A and B were each filled with the same amount of water. The temperature of water in cups A and B were 40oC and 5oC, respectively. They were left in the science room for forty minutes. Which one of the graphs correctly shows the change of temperature for the two cups of water?
- A.
Option 1
- B.
Option 2
- C.
Option 3
- D.
Option 4
Correct Answer
B. Option 2Explanation
The graph in Option 2 shows that the temperature of cup A decreases gradually over time, while the temperature of cup B increases gradually over time. This is consistent with the fact that cup A started at a higher temperature and cup B started at a lower temperature. Therefore, Option 2 correctly shows the change of temperature for the two cups of water.Rate this question:
