Physics F4C4 Frequent Asked Questions
Why is mercury used in thermometer ?
- Expand uniformly
- Opaque
- Doesn't stick to the glass wall
What is the function of constriction in thermometer?
- to avoid mercury returns back to the bulb
• When we took out the thermometer from the mouth, the temperature will drop
• With constriction, the temperature won't drop.
• Thus, we can read the temperature easily
What are the characteristics of a good thermometer?
1) have thin capillary tube
- increase sensitivity
2) thin wall of bulb
- absorb heat faster
3) small size of bulb
- absorb heat faster

Working principle of car radiator system
- combustion of fuel in the engine produces a lot of heat
- the pump forces the water to pass through the hot engine block areas and the water absorb heat
- the specific heat capacity of water is high
- it absorbs a lot of hear
- hot water flows to the radiator and is cooled through a cooling fin.

Modifications of grill
i) outer coating on grill body : ceramic / porcelain
- high specific heat capacity
ii) additional tool on the grill 1 : lid
- reduce heat loss
iii) additional tool on the grill 2 : fan
- supply more oxygen

Physics F5C2 Archimedes' Principle
Essay related to Hydrometer
Thin and long stem
- bigger range of liquid density
Made of glass
- not easy to erode
Large bulb
- greater buoyant force
High density of lead granules
- ensure the hydrometer always upright

Ramai nohh acc sunyi 😂😂😂 understandable 😌👍hahah
Sekadar perkongsian ja🤓✨
One thing I always ask myself sebelum post sesuatu di media sosial...❔
"Adakah benda yg saya tengah tunjuk ni benda baik? Atau adakah aku tengah menayangkan dosaku ?"🤔
Kalaulah aku tayangkan benda yg berdosa❤🔥 and then the people who look up to us think it's "RIGHT" to do it sebab kita pun buat😭nampak kecil tp impaknya besar. Kadang kita tak tahu who looks up to us😮 and without realizing mereka turut ikut apa yg kita buat. Benda ni boleh jadi dosa jariah dan akan sentiasa mengalir selagi orang lain melakukan dosa tersebut💢
So basically nasihat akk for adik2 semua is to "tapis" dulu apa yang kita nak kongsi dalam media sosial 🙈✨ apa2pun, thank you sudi baca nasihat akk yg tak seberapa ni🥰🌸
