The diagram shows a cylinder and a plunger. Ahmad filled the cylinder with some water as shown.
Why is Ahmad able to push the plunger downwards without air or water escaping?
air has weight
air occupies space
air has no definite shape
air has no definite volume
The diagram shows the change of state of water.
What are processes X and Y?

A ball tied to a string was released. It swung and hit the plastic bottle. The bottle fell down.
Which of the following shows the correct conversion of energy?
kinetic energy of ball → potential energy of ball → kinetic energy of bottle
potential energy of ball → kinetic energy of ball → kinetic energy of bottle
kinetic energy of ball → kinetic energy of bottle → potential energy of bottle
potential energy of ball → potential energy of bottle → kinetic energy of bottle
Which of the following is a possible effect on the water cycle when the temperature of the environment increases?
Condensation of water vapour decreases resulting in more rain.
Condensation of water vapour increases resulting in less clouds.
Evaporation of water increases resulting in more rain.
Evaporation of water decreases resulting in less water vapour in the air.
Two magnets A and B were placed close together with their north poles as shown.
When B was released, it moved along the surface of the floor.

An engineer set up a system using light bulb P and alarm Q to alert him when the temperature of an oven is too high. He used a metal rod that expands easily when temperature increases.
The table shows his results at different temperatures.
Which of the following is his set-up?
Bulbs A, B, C D were connected in a circuit hidden in a wooden box shown below. All the light bulbs lit when the circuit was closed.
Melissa removed one light bulb from the circuit each time and observed what happened to the rest of the light bulbs. Her observations are recorded in the table.
Which of the following correctly shows the circuit hidden in the wooden box?
Sulaiman placed two empty identical containers, K and M, both initially at room temperature on a table. He poured 500 cm3 of boiling water into container K and 250 cm3 of boiling water into container M.
The temperatures of water in K and M were recorded every minute for some time.
Which one of the following is the correct graph for his results?
A compass has a small magnet that can rotate freely as shown.
Four bar magnets were arranged such that they were attracted to one another. A compass was then placed near end P and the direction of the compass needle is as shown.
What would be the direction of the needle when the compass was placed at Q?
A spring is compressed and released at A. It moves to B as shown.
The graph shows the amount of different types of energy of the spring at A.
Which of the following graphs shows the amounts of different types of energy for the spring at B before it hits the ground?
Weishen has three sheets of different materials with different shapes cut in the middle. Only one sheet is made of a material that allows light to pass through.
He conducted an experiment in a dark room using the setup below.
Which of the following could be seen on the screen?
Wenkang sat on a ride at an amusement park.
When released, the stretched elastic ropes pulled Wenkang upwards as shown in Diagram 1. The elastic ropes stretched to a maximum length when he was at the highest point Q as shown in Diagram 2.
Which one of the following correctly explains why Wenkang was slowing down as he moved from P to Q?
Elastic potential energy was converted to heat by friction.
Elastic potential energy was converted to gravitational potential energy.
Elastic force was increasing as he was moving upwards.
Elastic force was pulling him in opposite direction to his weight.
Alex performed a jump. The three stages of his jump are as shown.
At which stage(s) did gravitational force act on him?
landing only
jumping and landing only
highest point and landing only
jumping, highest point and landing
Helen put a ceramic plate and a wooden bowl in the refrigerator overnight. When she removed the plate and the bowl from the refrigerator at the same time, her hands felt that the plate was colder than the bowl.
Which of the following explains why her hands felt that the plate was colder than the bowl?
The plate conducted heat better than the bowl.
The plate had a lower temperature than the bowl.
The plate had a greater surface area than the bowl.
The plate allowed cold air to escape faster than the bowl.
