Acetone has a lower boiling pt. than water because it has a higher vapor pressure. Liquids boil at the temperature where their vapor pressure is equal to the atmoshperic pressure. The temperature that acetone must get to, such that its v.p. is equal to the pressure of the atmosphere, is lower than what is required for water. Therefore, acetone has a lower B.P.

∙ 10y agoSimply because Acetone has a very very fast evaporation rate at ANY temperature. Plus it also is a great Dispersant as it break down oils. Same with the oils on your skin hence adding ti the cooling it does. I am aware of this as I worked for a resin factory who put the barrels of Acetone outdoors at 10-20 below 0 degrees F. It was used to clean our hands which were VERY cold once we got back indoors. We noticed at ANY temperature acetone's cooling traits.

Why does acetone have a lower surface tension than water?
water is more polar than acetone
Does caffeine dissolve in acetone?
Caffeine is soluble in water - but not HIGHLY soluble. You can dissolve a lot more caffeine in the same volume of water compared to what will dissolve in an equal volume of acetone. It dissolves better in hot acetone than in cold acetone.
Why cooling effect of ice at 0 degree Celsius is more than same amount of water at 0 degree Celsius?
Water at 0 oC is ice.
Why did water dried up first than acetone and alcohol?
water has a lower vapor pressure than alcohol or acetone, so it requires more heat energy to cause it to evaporate.
Is ethanol more volatile than acetone?
Acetone is more volatile than ethanol.
What weighs more water or acetone?
water
Why does acetone have a lower surface tension than water?
water is more polar than acetone
Water and ether are placed on the palms of both the hands which will cause more cooling ether or water?
Ether has a greater cooling effect than water when smeared on your hands because of its evaporation method. Ether gets its energy from your hands. So when it evaporates, the cooling effect is greater than water.
Does caffeine dissolve in acetone?
Caffeine is soluble in water - but not HIGHLY soluble. You can dissolve a lot more caffeine in the same volume of water compared to what will dissolve in an equal volume of acetone. It dissolves better in hot acetone than in cold acetone.
What is the effect of land heating and cooling more rapidly than water?
young money young money and we getting rich
Does ice have more cooling effect or cold water?
Most people would say ice, because it's colder, but I say neither is. Ice is just frozen water (which is a physical change), therefore, neither is better than the other.
Are crystallization and cooling the same thing?
Crystalization is more of a side effect of cooling. So no.
Why cooling effect of ice at 0 degree Celsius is more than same amount of water at 0 degree Celsius?
Water at 0 oC is ice.
What happens when connection for chilled water FCU Coil is reveresed?
the density of water is higher than the copper coil it doen not effect the gravitational force, because of the higher water density, the water try to achive the area of coil as we know the copper is the good conductor of cooling it absorb the cooling soon, we get the more cooling effect where air to be pump,if we does reverse connection in fcu so, cause of gavitional force water water will travel through the ciol soon and rusult into less cooling effect.as copared to previous connection
Why did water dried up first than acetone and alcohol?
water has a lower vapor pressure than alcohol or acetone, so it requires more heat energy to cause it to evaporate.
What makes the sea water cold?
cooling of seawater is caused by the evaporation of surface water which takes latent heat from surrounding water molecules, similar to the effect of sweating. Cooling of seawater is also due to brine acceptance, if the water becomes more saline, it will sink as it is heavier than the surrounding water masses and thus cooling as water which becomes more dense has a lower maximum temperature, and pressure causes water to become colder.
Is the vapor pressure of water and acetone different?
The three liquids have different densities. Water has a density of 1g/mL. Acetone has a density of 0.791g/mL. Ethanol has the density of 0.789g/mL. Also, ethanol has the strong smell that resembles one of nail polish remover. Ethanol is used in alcohol. Acetone is practically a type of acid.
