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.
Does ice float on water because of cohesion?
Ice floats on water because it is less dense than liquid water. When water freezes and forms ice, the water molecules arrange themselves in a crystalline structure that causes the ice to be less dense. This is why ice floats on water rather than sinking.
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 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 is the effect on boiling point if acetone is mixed in water?
The boiling point of water becomes decreased because acetone is highly volatile liquid its molecules decrease the effect of hydrogen bonding in water molecules therefore water becomes evaporated easily.
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.
Is acetone thicker than water?
No, acetone is about the same viscosity as water.
Does ice float on water because of cohesion?
Ice floats on water because it is less dense than liquid water. When water freezes and forms ice, the water molecules arrange themselves in a crystalline structure that causes the ice to be less dense. This is why ice floats on water rather than sinking.
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.
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.
What is the advantage of acetone over ethanol in recrystallization?
Acetone has a lower boiling point than ethanol, making it easier to remove from the crystallized compound. Acetone also tends to dissolve impurities better than ethanol, resulting in purer crystals. Additionally, acetone is less likely to form hydrates with water compared to ethanol, which can interfere with the recrystallization process.
Do different liquids have a different amount of cohesion?
Yes, different liquids have different levels of cohesion based on their molecular properties. Liquids with stronger intermolecular forces, like water, exhibit higher cohesion resulting in stronger surface tension. In contrast, liquids with weaker intermolecular forces, like alcohol, have lower cohesion and reduced surface tension.
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 aluminum float on water and ethanol but sinks on acetone?
H bonds present between the h2o molecules creates surface tension greater than that present in other liquids.
What is is less dense then water?
Most commonly available substances that are less dense than water is oil, alcohol and plastic. In fact, a number of organic solvents such as acetone, methanol and methylene chloride are also less dense than water. In addition, a number of different kinds of polymer are "lighter" than water, too.Hmm... potassium and sodium? :DCredit: To the other answer linked below.Read more: What_substances_are_less_dense_than_normal_water
