Why is water mixed alcohol lighter than fresh water?
The density of alcohol is less than that of water.
Why does alcohol float on the oil?
The alcohol is less dense than the water, so it floats up to meet the density needs.
Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?
Sodium chloride increase the surface tension of water and methanol decrease the surface tension of water.
Why do plants in dry areas have leaves with reduced surface area?
many plants developed a wazy surface cuticle to reduce water loss
How does Alcohol inhibit salivary amylase?
Alcohol when ingested dehydrates the body. The body will try an conserve water which will allow for less saliva production.
Why is water mixed alcohol lighter than fresh water?
The density of alcohol is less than that of water.
Why did the needle float easier on the water than on alcohol?
Water has a much stronger surface tension than alcohol does. Because water molecules are highly polar, they have a relatively strong attraction for each other (as compared to the attraction that the molecules of most other liquids have for each other) and this creates a kind of limited solidity on the surface, called surface tension. The alcohol molecule is much less polar and has much less attraction for other alcohol molecules, and correspondingly less surface tension. It is the surface tension that can support a needle on the surface of the water, despite the fact that the needle is denser than water and is not buoyant enough to float.
Why is surface tension of water higher than surface tension of methane?
Hydrogen bonding. Water is a polar molecule so it is slightly negatively and positively charged on different ends and this leads to cohesion of the molecules; one to another. Alcohol is nonpolar.
What happens if you mix chlorine bleach and rubbing alcohol?
Answer#1The alcohol, being less dense will float on top. They do not react. This answer is nonsense. Alcohol and bleach will mix, and they react, but not in a way that will kill you. Alcohol is less dense than water or bleach (water plus sodium hypochlorite) but alcohol and water do mix... mixed drinks, anyone?
How can an ice cube float in a glass of water?
ice cube floats in water because it is dense and heavy if u compare water to alcohol then an ice cube will sink in the alcohol because alcohol is less dense which means its light.
What liquid has a density less than water?
Volatile liquids such as alcohol and ethanol have less density than water. They also evaporate faster than water does.
What happens if the item is less dense than water?
This item float on the surface of water.
Why does oil float on the surface of water?
Because oil is less dense than water.
Why does alcohol float on the oil?
The alcohol is less dense than the water, so it floats up to meet the density needs.
What liquid is less dense than alcohol?
hmmm, water??? lol, joking!
Why was the leaf placed in alcohol after being in boiling water?
The leaf was placed in alcohol wafter being placed in the boiling water to extract the green pigment from the leaf.
Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?
Sodium chloride increase the surface tension of water and methanol decrease the surface tension of water.
