A student wants to take a particularly accurate measurement of the volume of liquid in a measuring cylinder.

Which of the following procedures would make her measurement less accurate?

  • Putting her eyes level with the height of the measurement to be taken.

  • Reading the liquid level from the bottom of the meniscus.

  • Using the largest measuring cylinder she could find.

  • Using a set-square to make sure the cylinder is perfectly vertical.

A person wishes to roast a chicken. The chicken requires 1 hour and 20 minutes in the oven to be properly cooked.

The oven must be switched on 10 minutes before any food is put in, in order to pre-heat, and reach the correct temperature for cooking.

The chicken needs to be ready at 4:30 pm. At what time must the oven be switched on?

  • 2:10 pm

  • 3:10 pm

  • 2:00 pm

  • 3:00 pm

A particularly diligent student wants to measure the volume of some liquid for an experiment. She has two measuring cylinders available, a large 250 ml one and a small 50 ml one. The liquid will fit into either of the two measuring cylinders.

As expected, the liquid forms a meniscus where it touches the sides of either measuring cylinder.

Which cylinder should the student use to get the most accurate result, and from where should she measure the liquid level?

 

Measuring cylinder

Reading taken from

A

large

Top of meniscus

B

large

Bottom of meniscus

C

small

Top of meniscus

D

    A scientist is trying to determine the volume of three identical pieces of a new material. She places them in a measuring cylinder, as shown in the diagram.

    The first cylinder shows the level of water in the measuring cylinder before the pieces are added, and the second cylinder shows the measuring cylinder with the pieces of the new material inside.

    q4-medium-mcq-1-1--physical-quantities-and-measurement-techniques-cie-igcse-physics

    What is the volume of each piece of the new material?

    •  30.0 cm3

    • 13.3 cm3

    • 16.7 cm3

    • 40.0 cm3

        A student is trying to see how quickly they can run 5.0 km on a standard 400 m running track.

        They reason that, if they know how fast they can run one lap, they can assume they will run at the same speed for 5.0 km, and can calculate their predicted time.

        They, correctly, reason that they will not be able to maintain their initial pace throughout the whole 5.0 km, so they decide to time lap 5.

        The diagram shows the reading on the stopwatch at the beginning and the end of lap 5.

        q2-hard-mcq-1-1--physical-quantities-and-measurement-techniques-cie-igcse-physics

        Calculate how long it should take the student to run 5.0 km.

        • 36 minutes 52.5 seconds

        • 24 minutes 22.5 seconds

        An Olympic cyclist rides around a velodrome track 5 times.

        The diagram below shows the reading on the stopwatch, which was used to time the laps. Unfortunately, the person using the stopwatch started it a little early, so the stopwatch reads 2 seconds when the cyclist starts.

        q3-hard-mcq-1-1--physical-quantities-and-measurement-techniques-cie-igcse-physics

        What is the average time to complete one lap of the velodrome?

        • 16.24 s

        • 14.04 s

        • 15.84 s

        • 15.21 s

        A student uses a ruler to determine the circumference of a wooden dowel.

        She puts a mark onto the dowel, then rolls it along the ruler three times, before reading the position on the ruler at which it stopped.
