J
(ii) Give one reason for the answer in 3(b)(i). Beri satu sebab jawapan 3(b)(i).
…………………………………………………………………….[1 mark]
J(dark surface) gives out /radiate heat better than K (white surface)J(permukaan hitam) mengeluarkan haba lebih baik dari K(permukaan putih)
Cooking utensil // electric iron Alatan memasak// seterika
To prevent reduce absorption of heatUntuk mengelakkan penyerapan haba
Frictional force/ daya geseran
Produce heat// slows down movement//wears away materialsMenghasikan haba//perlahankan pergerakan
Sand/ pasir
Wear out/ tayar menjadi haus
Avoid skidding//give good grip//easy to slow down or stop the carMenggelakkan tergelincir
Put some oil/lubricantMeletakkan sedikit minyak
Based on your observation, state the way to separate the components of
the mixture in P,Q,R and S.
P : …………………………………........................Q : …………………………………........................ R : …………………………………........................S : …………………………………........................

Filtering/ Menuras
Using the magnet/ menggunakan magnet
Heating / memanaskan
Sieving/ Menapis

When the temperature increases, the reading of the Bourdon gauge increases//
The higher the temperature, the higher the air pressure/ reading of the Bourdon gauge
Jika suhu meningkat, bacaan tolok Bourdon juga akan meningkat
Semakin tinggi suhu, semakin tinggi tekanan udara
(c) Based on the graph drawn in 8(b)(iii). (i) State the relationship between the temperature and the
reading of the Bourdon gauge.……………………………………………………………………………………….
[1 mark](ii) Predict the reading of the Bourdon gauge if the
temperature is more than 60°C. …………………………………………………………………….
[1 mark](iii) State what happen to the reading of the Bourdon gauge if
the flask is heated for a long time. …………………………………………………………………….
[1 mark]
The higher the temperature, the reading of the Bourdon gaugeSemakin tinggi suhu, semakin tinggi bacaan tolok Bourdon
More than 96/ lebih 96
The reading increases and stop at a certain point.Bacaan akan meningkat dan berhenti pada tahap tertentu
(d) State the variables involved in this experiment.Nyatakan pembolehubah yang terlibat
(e) Based on the experiment, state the operational definition of air pressure.Berdasarkan eksperimen, nyatakan definisi operasi bagi tekanan udara.……………………………………………………………………………………………
Manipulated variablePembolehubah manipulasi
Responding variablePembolehubah Bertindakbalas
Temperature/ suhu
Reading of the Bourdon gauge /bacaan Tolok Bourdon
Air pressure is the reading of the Bourdon gauge/ Tekanan udara ialah bacaan Tolok Bourdon
