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.
What else can I help you with?
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 does acetone have a lower surface tension than water?
Acetone has a lower surface tension than water because it has weaker intermolecular forces due to its molecular structure. The molecules in acetone are less able to attract each other compared to water molecules, resulting in a lower surface tension.
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.
Why is acetone cooler than water?
Acetone tends to evaporate faster than water, which causes it to have a cooling sensation when it comes in contact with the skin. This is due to the higher volatility of acetone compared to water, leading to a more rapid evaporation process that removes heat from the skin, resulting in a cooling effect.
What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
What weighs more water or acetone?
Water weighs more than acetone. This is because water has a higher density than acetone, meaning that a given volume of water will have a greater mass compared to the same volume of acetone.
What is the effect of acetone on the solubility of cholesterol?
Acetone can increase the solubility of cholesterol by dissolving it more effectively. This is because acetone is a polar solvent that can interact with the cholesterol molecules, helping them to dissolve more easily.
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.
Why does acetone have a lower surface tension than water?
Acetone has a lower surface tension than water because it has weaker intermolecular forces due to its molecular structure. The molecules in acetone are less able to attract each other compared to water molecules, resulting in a lower surface tension.
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
Does ice have more cooling effect or cold water?
Ice has a greater cooling effect than cold water, as it absorbs more heat from its surroundings in order to melt and reach the same temperature as the water. Cold water, on the other hand, will only cool down the surrounding area until it reaches thermal equilibrium.
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.
