Ether at room temperature is placed in a flask connected by a rubber tube to a vacuum pump the pump is turned on and the ether begins to boil why?
Because the pressure of the atmosphere in the flask is lowered by the vacuum; a liquid will reach it's boiling point when the pressure of the atmosphere is equal to or less than the vapor pressure of the liquid.
What is a boiling flasks proper name?
k Vacuum flask
A balloon placed in which condition will be the largest?
High temperature and vacuum.
If the pressure in a sealed container is reduced can boiling point of a fluid be also reduced?
Yes. You can, for example, boil water at room temperature if you apply a vacuum pump to the container. However, if it was ONLY a sealed container (reduce the pressure and then take the vacuum pump away), the vapor increases the pressure and the whole thing comes to equilibrium and stops boiling.
If you have a very heat sensitive liquid that will decompose if it is overheated How could you purify it by distillation without applying excessive heat?
Usually by using a vacuum pump or a water aspirator, the boiling point of the liquid is reduced.

Why Stop boiling water Vacuum Chamber With the continuation of the vacuum pump work And vacuum pressure gauge -30 in hg Thank you?
You want to stop boiling water Vacuum Chamber because of the vessel seal. If the pump is boiling it will stop at the point of equilibrium.
Why higher boiling hydrocarbonates are distilled under vacuum condition?
because they decompose at higher temperature.. under vacuum they can be boiled at lower temperature than their boiling point

How could you demonstrate boiling point?
A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.
What is a vacuum distillation?
When pressure is reduced the boiling point will also reduce
How do you Make the water continues to boil in a vacuum chamber Because the water is boiling and then stops boiling How do I manage the balance point?
You can manage the boiling point by managing your heating element.
What happens when water is placed in vacuum?
You burn up the motor.
Is manifold vacuum increased or lowered by size of port?
bigger port, lower vac, smaller port, highr vac..........
What is the effect of negative pressure in fluid flow?
The effect of negative pressure or vacuum, lowers the boiling point of fluids. Water will boil at room temperature in a vacuum. Automotive cooling systems are pressured to achieve the opposite result of raising the boiling temperature.
What is a boiling water canner?
Typically called a "water bath canner" it consists of a large cauldron style pan with a removable rack to hold canning jars. Once sterilized canning jars are filled with food items and brand new jar lids are placed on each (with reusable rings finger tightened around the top of them) they are placed in the rack and lowered into boiling water. Most items call for 20 minutes of boiling - directions are given with canning jars - and a specialized jar remover tool can be used to take them out one at a time and set aside to cool. As the filled jars cool the lids will vacuum seal to the top of the jars forming a slight indentation on the top and a "pop" sound. The food is now preserved for storage without refrigeration. The appropriate food for this type of canning is jellies, jams, pickles and NOT meat containing items which are "pressure canned".
What is a vacuum mold?
A vacuum mold is a shape that is placed in a vacuum molding machine to produce the finished piece. A hot plastic sheet is lowered onto the mold, and then air is vacuumed out from underneath. This pulls the soft plastic sheet down over the mold, and the plastic takes the shape of that mold. Cold air is blown over the setup for a short time, and the molded plastic sheet, with its molded shape formed in it, is lifted off the mold and sent on for further work.
