…………………………………………………………………….[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

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
