A pressure gauge is an instrument that measures the pressure in a vessel‚ a line‚ or whatever the pressure gauge is connected to. A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside‚ there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is

heating a substance until it is vaporized‚ cooling the vapors‚ and collecting the condensed liquid is the basis of a commonly used purification technique called distillation. Vapor Pressure and Boiling Point If a liquid is placed in a closed container‚ some molecules at the surface of the liquid evaporate into the space above the liquid. If this didn’t happen‚ you wouldn’t be able to smell a liquid. Once vaporized‚ some of the molecules in the vapor condense back into the liquid in a competing process

Academic Pressure In the movie The Dead Poet Society‚ Neil‚ the protagonist was getting academically pressured by his parents‚ his dad especially. He was told to get all A’s or he would be punished. He was threatened at the beginning to be forced to leave that field he wanted to study‚ but he did not listen to his dad. Academic pressure plays a big role in why some people have anxiety‚ or get really mad at themselves if they do something wrong or even get a bad grade. In my perspective I believe

Experiment 2: Isolation of Eugenol from Cloves Background; Readings on Vapor pressure‚ Raoult’s Law from TRO: A mixture of the essential oils‚ eugenol and acetyleugenol‚ will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution is shaken with aqueous sodium hydroxide‚ which will react with eugenol‚ to yield the sodium salt of eugenol in the basic

under peer pressure. Orwell‚ like many people‚ faced peer pressure‚ which lead to a dead elephant. Even though his actions were justified‚ he knew it was not right and he had to live with that for the rest of his life. Peer pressure is a big problem in our world today‚ especially with our younger generations. This could be due to the lack of parental support and presence‚ but whatever the cause may be the result can be very devastating. Children around the world are being pressure in to things

property of changing readily from a solid or liquid to a vapor or the tendency of a substance to vaporize. It is directly related to a compounds vapor pressure. A compound with higher vapor pressure vaporizes sooner than a compound with a lower vapor pressure. In the course of distillation the substances are heated to a boiling point in a glass container known as the pot. A condenser that is cooled by flowing water is used to cool the vapors produced as they re-liquefy and are collected in a separate

a compound A‚ with vapor pressure 400mmHg at 50oC‚ mixed with 3 moles of compound B‚ with vapor pressure 480mmHg at 50oC to form a homogeneous solution. What is the vapor pressure of mixture at 50oC? XA =moles of A\total No. of moles XA =1\4 XB=3\4 Ptotal=PAoXA+PBoXB =400*1\4 + 480*3\4 = 460mmHg 2. Why should a distilling flask be filled not less than 1\3 filled or more than 2\3 full? This is to allow the liquid being heated room to expand as it turns to a vapor. Also‚ 1\3 would
