The change in viscosity of silicone oil very small with change in temperature as compared to ordinary lubricants. If temperature is dropped from 100-0*c, viscosity of petroleum increases to 100 fold while of silicone increases to less than 4 folds only. Due to these reasons silicone oils are preferred over ordinary lubricants.

Why does silicone smell like vinegar?
The vinegar-like smell from silicone is due to the presence of acetic acid, which is a byproduct of the curing process of the silicone material. This odor typically dissipates over time as the silicone fully cures and stabilizes.
Why is silicon preferred over germanium?
Silicon is generally preferred over germanium for electronic applications because it has a higher bandgap energy, allowing for the creation of more efficient and faster electronic devices. Silicon is also more readily available and easier to work with in terms of manufacturing processes compared to germanium. Additionally, silicon has better thermal stability and higher breakdown voltage, making it more reliable for long-term applications.
Why dilute sulphuric acid is preferred while testing anions over dilute HCl?
Dilute sulfuric acid is preferred over dilute HCl for testing anions because it can help differentiate between chloride ions and sulfate ions by forming precipitates with certain anions. Sulfuric acid also provides a stronger acid environment for reactions, allowing for more distinct precipitation reactions to occur during the testing process.
Why can graphite used in a pencil?
Graphite is used in pencils because it is soft, leaving a visible mark on paper without scratching it. It also has good electrical conductivity, making it suitable for other applications like lubricants and batteries.
Is it preferable to pour concentrated sodium hydroxide over sulfuric acid spilled on the floor?
No. The reaction of sodium hydroxide with sulfuric is more exothermic. And hence it is preferred to pour a solution of sodium bicarbonate or potassium bicarbonate in the case of spills.

What are the difference between ordinary share holder and preference share holder?
The three biggest difference between common and preferred shares are: 1) Preferred shareholders take priority over common shareholders in the event of a company is liquidated. 2) Preferred shareholders typically have more voting rights than common shareholders. 3) Preferred shares typically pay higher dividends than common shares.
How do lubricants help to reduce friciton?
The molecules of lubricants can slide over each other due to the weak attractions between them and hence they allow the machine parts to slide over each other smoothly reducing friction and damage.
Why interval estimates are preferred over point estimates?
Interval estimates are generally to be preferred over point estimate
How may the lubricants manufacturers be said to have an edge over general refiners?
specialized equipment and multiple blending agents are more difficult to maintain in an integrated refining plant than in a lubricants plant.
How is silicone sealant for roofing different from other roofing materials?
Silicone stays flexible where as standard roofing tar hardens and cracks over time.
What are the characteristics of preference shares and ordinary shares?
Preferred shares in a company represent a larger interest in the company than common shares do. Preferred shareholders are paid dividends first, regularly and typically at a higher rate than common shareholders, and if the company declares bankruptcy they have priority over common shareholders who are last in line to get paid.
Why copper is preferred over sodium?
yes
What is the transitivity of preferences?
Transity of preference is one of the axioms common to most models of decision theory. It means that if choice A is preferred over choice B and choice B is preferred over choice C, then choice A should be preferred over choice C.
While dieting is the intake of chicken preferred or beef?
