Fatimah ingin mengetahui sama ada jumlah air mempengaruhi ketinggian anak pokok kacang selepas dua minggu. Dia memberikan 10 mL, 20 mL dan 30 mL air kepada tiga buah pasu yang sama saiz dan berisi jenis tanah yang sama. Apakah pemboleh ubah bergerak balas dalam penyiasatan ini?Fatimah wants to find out whether the amount of water affects the height of bean seedlings after two weeks. She gives 10 mL, 20 mL and 30 mL of water to three pots of the same size that hold the same type of soil. What is the responding variable in this investigation?

Jumlah airAmount of water
Ketinggian anak pokok selepas dua mingguHeight of the seedlings after two weeks
Jenis tanahType of soil
Saiz pasuSize of the pot

Show answerHide answer

The responding variable is the one we measure because of the change we make. Fatimah measures the height of the seedlings. The amount of water is the manipulated variable; the type of soil and the size of the pot are constant variables.

Makan makanan yang digoreng setiap hariEating fried food every day
Minum banyak minuman yang manisDrinking a lot of sweet drinks
Duduk tanpa bergerak untuk masa yang lamaSitting still for a long time

Show answerHide answer

Regular exercise, and eating less food that is high in fat and sugar, keep the heart and blood vessels healthy. Fried food and sweet drinks do the opposite.

Sebahagian besar hutan dibersihkan untuk membina sebatang jalan raya. Jadual menunjukkan bilangan hidupan di hutan itu sebelum dan selepas jalan raya dibina.

Hidupan / Living thing	Sebelum / Before	Selepas / After
Pokok buah-buahan / Fruit trees	300	120
Monyet / Monkeys	80	35
Burung enggang / Hornbills	24	10

Antara yang berikut, yang manakah menerangkan dengan paling baik mengapa bilangan monyet berkurang?A large part of a forest is cleared to build a road. The table shows the number of living things in the forest before and after the road is built. Which statement explains best why the number of monkeys decreased?

Monyet makan lebih banyak buah apabila pokok buah-buahan berkurang.Monkeys eat more fruit when there are fewer fruit trees.
Burung enggang memakan monyet apabila buah berkurang.Hornbills eat monkeys when there is less fruit.
Monyet kehilangan makanan dan tempat tinggal apabila pokok ditebang.Monkeys lose their food and shelter when the trees are cut down.
Monyet berpindah kerana burung enggang berkurang.Monkeys move away because there are fewer hornbills.

Show answerHide answer

The fruit trees fell from 300 to 120, so the monkeys lost food and shelter and their number fell. Hornbills also fell, so they cannot be eating more monkeys, and nothing in the table suggests the monkeys left because of the hornbills.

Rajah 1 menunjukkan sebuah termometer yang digunakan untuk mengukur suhu air panas. Berapakah bacaan termometer itu?Diagram 1 shows a thermometer used to measure the temperature of hot water. What is the reading of the thermometer?

A horizontal thermometer with long marks labelled 50, 60, 70, 80 and 90 degrees Celsius and a short mark every 2 degrees. The red liquid ends at the third short mark after 70. — Rajah 1Diagram 1

73 °C
76 °C
78 °C
80 °C

Show answerHide answer

There are 5 spaces between 70 and 80, so each small mark is 2 °C. The liquid ends at the third mark after 70: 70 + 3 × 2 = 76 °C.

Rajah 2 menunjukkan susunan zarah air di dalam sebuah bekas sebelum dan selepas proses P. Apakah proses P dan apakah yang berlaku kepada haba air itu?Diagram 2 shows the arrangement of the particles of water in a container before and after process P. What is process P and what happens to the heat of the water?

Pembekuan; air kehilangan habaFreezing; the water loses heat
Peleburan; air menerima habaMelting; the water gains heat
Pendidihan; air menerima habaBoiling; the water gains heat
Kondensasi; air kehilangan habaCondensation; the water loses heat

Show answerHide answer

The particles change from less packed with no pattern (liquid) to closely packed and orderly (solid). A liquid becoming a solid is freezing, and the water loses heat.

[1 mark] (d)Mei Ling meletakkan sebatang paku besi yang lain di dalam sebuah balang tertutup yang berisi kalsium klorida kontang. Ramalkan keadaan paku itu selepas dua minggu. Berikan sebab.Mei Ling puts another iron nail in a closed jar that contains anhydrous calcium chloride. Predict the condition of the nail after two weeks. Give a reason.

Show answerHide answer

The nail does not rust, because there is no water / the calcium chloride absorbs moisture so the air is dry1

Iron rusts only when both water and air are present. Anhydrous calcium chloride absorbs moisture.
