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???

ProfessorRubbing alcohol is less dense than water because it has a lower molecular weight and fewer hydrogen bonds, giving it a lower mass per unit volume than water. Additionally, the presence of the hydroxyl group (-OH) in rubbing alcohol contributes to its lower density compared to water.

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, water is not the least dense liquid. Liquid helium, with a density about one tenth that of water, is an example of a liquid that is 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.
Why is water mixed alcohol lighter than fresh water?
Water mixed with alcohol is lighter than fresh water because alcohol is less dense than water. When alcohol is added to water, the overall density of the mixture decreases due to the lower density of alcohol, making the mixture lighter than fresh water.
Why does 1 cup water 1 cup rubbing alcohol equal less than 2 cups?
When you mix 1 cup of water with 1 cup of rubbing alcohol, the total volume of the mixture will be less than 2 cups due to a phenomenon called "partial molar volume." Water and rubbing alcohol have different molecular sizes and structures, leading to a decrease in the total volume when mixed together. The molecules of water and rubbing alcohol pack differently when in close proximity, causing them to occupy less space collectively compared to when they are separate. This results in the final volume being less than the sum of the individual volumes of water and rubbing alcohol.
