Why is rubbing alcohol less dense than water?
If you filled a 1L bottle with water and another 1L bottle with rubbing alcohol, which bottle would feel heavier? Use your data to thoroghly explain why. The rubbing alcohol would be heavier because water's density is 1.0, and rubbing alcohol's density is much more than that. Right???
Does rubbing alcohol or pepsi evaporate?
At RT, rubbing alcohol would evaporate in a quicker time as its boiling point is less than that of water.
Is water the least dense than all the liquids?
No. Several liquids, including gasoline, oil and alcohol, are less dense.
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 is rubbing alcohol made out of?
Active Ingredients Ethyl Alcohol by Volume 70% Ingredients Denatonium Benzoate , Methyl Isobutyl Ketone , Water The ingredients will be listed on the bottle. There are two standard kinds of rubbing alcohol: (1) one made with isopropryl alcohol, which has a certain toxicity but is more pleasant or neutral smelling; and (2) one made with ethyl alcohol with an added denaturing agent to make it inedible. The ethyl alcohol (ethanol) variety has a bitter or sour or unpleasant smell, and is therefore much less popular than the isopropryl alcohol variety. This is why even though the pharmaceutical definition for "rubbing alcohol" is denatured ethyl alcohol, isopropryl alcohol is far more available commercially and is also labeled as "rubbing" alcohol. The uses of both varieties are the same, although isopropryl alcohol, because of its inherant toxicity, carries warnings about overuse and safe handling. According to Wikipedia.org1: Common, over the counter "Rubbing Alcohol" in pads or in fluid form is generally 60-70% solution of isopropanol in water. Although Isopropanol is sometimes sold as "Isopropyl Rubbing Alcohol, 70%" and "Isopropyl Rubbing Alcohol, 99%" (harder to find but generally more useful for experimenters & cleaning uses), there is no isopropyl alcohol in the United States Pharmacopeia formula for Rubbing alcohol, U.S.P.. It is used as a disinfectant, and is a common solvent.
Is glycerin less dense than water and cooking oil?
No, it is more dense than water and cooking oil.
What type of liquid has a close density to vegetable oil?
Rubbing alcohol is less dense, it will float on top ofvegetableoil.
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?
Is oil less dense then water?
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.

Pure ethanol is less dense.
Does rubbing alcohol or pepsi evaporate?

Why is rubbing alcohol less dense than vegetable oil?
The density of materials is depending on the chemical composition, chemical structure, temperature, pressure. Between rubbing alcohol and vegetables oils many differences exist. Note also that more than 1oo types of vegetable alimentary oils are used.
Why does ice float on water but sinks in methylated spirits?
The density of rubbing alcohol is 75% that of water. Thus ice (frozen water which is roughly equal in density to liquid water), sinks in rubbing alcohol since it has more mass per cubic millimeter than the alcohol does. In order to float, the object would have to be less dense than the alcohol per cubic space.
Why do you have to use alcohol to extract DNA?
Because it is less dense than the alcohol and make it float
Does rubbing alcohol evaporate faster when cooled?
the atmosphere determines rate of evaporation. if the atmosphere is as dense as a liquid within the atmosphere there is no evaporation at all. on earth, cooler atmospheres are generally less dense, so it's not cooling the liquid alcohol as much as providing it with a supply of less dense atmosphere that will make a liquid, alcohol, evaporate faster. on the extreme, putting a liquid into a vacuum will cause it to almost immediately evaporate, a.k.a. standardize the temperature and pressure of its atmosphere. there is really no such thing as evaporation as much as there is homogenization, standardization, of its atmosphere.
