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.

How does the presence of alcohol on silicone affect its durability and performance?
The presence of alcohol on silicone can weaken its durability and performance. Alcohol can degrade the silicone material over time, making it less resistant to wear and tear. This can lead to a decrease in the overall performance and lifespan of silicone products.
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.
Will nitric acid attack silicone tubing?
Yes, nitric acid can react with silicone tubing, causing degradation and potential damage to the tubing over time. It is recommended to use tubing that is compatible with nitric acid or to find an alternative material for handling this chemical.
Why is an Erlenmeyer flask preferred over a beaker for recrystallization?
An Erlenmeyer flask is preferred over a beaker for recrystallization because its conical shape allows for better control of evaporation and minimizes the loss of solvent during the process, leading to more efficient and effective recrystallization.
Why silicon is preferred over other semi conductors?
Silicon is preferred over other semiconductors mainly due to its abundance, stability, and relatively simple manufacturing process. Its well-established technology and extensive infrastructure also make it a popular choice for making electronic devices. Additionally, silicon has good electrical properties that allow for efficient conduction of electricity in a wide range of applications.

What are swimming caps made of?
Swimming caps can be made out of Latex or Silicone. Silicone is most preferred as it stretchs over the head easier, rather than latex caps.
Why is PC preferred over laptop?
if you mean why is a desktop preferred over a laptop. then i would answer that they aren't and that laptops are preferred because of their convenience
Can you paint over silicone caulk?
No, it is not recommended to paint over silicone caulk as the paint may not adhere properly to the smooth and water-resistant surface of the caulk.
What is a substance blown into locks to lubricate their mechanisms?
The substance commonly blown into locks to lubricate their mechanisms is typically a graphite powder or a specialized lock lubricant. Graphite is favored because it reduces friction and does not attract dust and debris, which can cause the lock to jam. Some people also use silicone-based lubricants for similar purposes. It’s important to avoid using oil-based lubricants, as they can attract dirt and grime over time.
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
Do lubricant expire?
Yes, lubricants can expire. Most lubricants have a shelf life, typically indicated by an expiration date on the packaging. Over time, lubricants may degrade in quality, losing their effectiveness or becoming less safe to use. It's best to check the expiration date and store lubricants in a cool, dry place to maximize their longevity.
How does the presence of alcohol on silicone affect its durability and performance?
The presence of alcohol on silicone can weaken its durability and performance. Alcohol can degrade the silicone material over time, making it less resistant to wear and tear. This can lead to a decrease in the overall performance and lifespan of silicone products.
How is silicone sealant for roofing different from other roofing materials?
Silicone stays flexible where as standard roofing tar hardens and cracks over time.
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.
