Examples of volatile liquids?
A Volatile liquid is any liquid that can be vaporised quickly. This does not mean they are necessarily flammable. Examples - Water Chloroform Hexane Acetone Petrol methylated spirits alcohol..........
Which evaporates faster alcohol or ether?
There are two reasons for this; {1} boiling point: Tthe boiling point of water is greater than that of ether. So when the boiling point is greater then the vapour pressure will be low. {2} intermolecular forces: The second is intermolecular forces. When intermolecular forces are greater then the the boiling point will be greater and if boiling point is greater then the vapor pressure will be low. The inter molecular forces of water is greater than that of ether and so the vapour pressure will be low and and boiling point will be greater.
Does vapour pressure depend upon the nature of a liquid?
because nature of liquid means a attractive forces less attractive forces means low vapour pressure
Why the vapour pressure of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
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.
Why does acetone evaporate so fast?
Acetone evaporates faster than alcohol and water because alcohol and water contain intermolecular hydrogen bonding but acetone does not. This is the reason alcohol and water have higher boiling point than acetone and evaporate slower than it.
Why vapour pressures of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
Why do clouds form when air rises?
As air rises, it cools adiabatically. This is the result of less pressure being applied to a parcel of air as it rises in altitude (as there is less air pressing down above it). As the air cools, its capacity to suspend water vapour decreases, and it may approach one hundred percent relative humidity, also known as dew point. Dew point is the temperature at which water vapour will condense in air at a given pressure. The condensed water vapour will form clouds, which may cause precipitation.
Do water vapour has volume?
But of course the vapour of the water have the volume. but it is a less than the water itself goodbye.
Can acetone be used in recrystallization?
Yes. One method used allows dissolving your compound in a mix of acetone and toluene for instance. as the acetone evaporates, the mix becomes less polar and the compound recrystallises.
Why evapourate at a low pressure?
Reducing the air pressure allows the molecules to escape
Why have penthrane and enthrane replaced diethyl ether as a general anesthetic?
penthrane and enthrane replaced diethyl ether because both of them are less flammable
