What else can I help you with?
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 are the differences between simple, fractional, and vacuum distillation methods?
Simple distillation is used to separate liquids with significantly different boiling points, while fractional distillation is used for liquids with closer boiling points. Vacuum distillation is used at lower pressures to lower the boiling points of substances.
How is a vacuum pump utilized in the distillation process?
A vacuum pump is used in the distillation process to lower the pressure inside the distillation apparatus. This helps to lower the boiling point of the liquid being distilled, making it easier to separate different components based on their boiling points.
What is a boiling flasks proper name?
The proper name for a boiling flask is a round-bottom flask. These flasks are typically made of glass and have a spherical bottom to allow for even heating and boiling of liquids.
What happens to water when placed in a vacuum?
When placed in a vacuum, water will start to evaporate due to the reduced air pressure. As the pressure decreases, the water molecules gain enough energy to break free from the liquid and turn into water vapor.

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 FEV distillation?
FEV distillation, or fractional distillation in a vacuum, is a method used to separate substances with close boiling points. By lowering the pressure in the distillation apparatus, the boiling points of the components are also lowered, allowing for more efficient separation. This technique is often used in industries such as oil refining and chemical processing.
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 are the differences between simple, fractional, and vacuum distillation methods?
Simple distillation is used to separate liquids with significantly different boiling points, while fractional distillation is used for liquids with closer boiling points. Vacuum distillation is used at lower pressures to lower the boiling points of substances.
What happens when water is placed in vacuum?
You burn up the motor.
Why use vacuum distillation on compounds with high boiling points?
Vacuum distillation lowers the boiling point of the compound by reducing the pressure in the system, which helps prevent thermal degradation or decomposition of the compound at high temperatures. This is especially useful for compounds with high boiling points that may decompose or react at their normal boiling points.
Is manifold vacuum increased or lowered by size of port?
bigger port, lower vac, smaller port, highr vac..........
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".
