No, alcohol does not help hairspray evaporate. In fact, it does the complete opposite. Because hairspray is made up of mostly alcohol, adding more alcohol will just end up distributing the hairspray even more so.
Alcohol starts evaporating at a lower temperature than water. therefore it evaporates quicker
Pure alcohol evaporates faster than pure water. A mixture of the two will slow the evaporation of the alcohol.
water has a lower vapor pressure than alcohol, so it requires more heat energy to cause it to evaporate.
The Molasses Act of 1733 The trouble was how it would effect the making of Rum.
No, it will evaporate slower. When salt or another nonvolatile solute is added to water it raises the boiling point, making it more difficult to evaporate.
Water evaporates slower than rubbing alcohol because it is a more stable substance. The bonds in water are very strong.
It is more likely to go "good" (turn to alcohol) than to go bad. It can crystallize though.
water has a lower vapor pressure than alcohol or acetone, so it requires more heat energy to cause it to evaporate.
No, they do not mix.
Alcohol evaporate faster than water because water has extensive hydrogen bonding between its molecules which results in its high boiling point whereas in alcohol, amount of hydrogen bonding is smaller as compared to water. This makes the boiling point of alcohol less than water.
The noun molasses is a mass (non-count) noun, a word for a substance. Substances are expressed as some molasses, more molasses, a cup of molasses, two cups of molasses, bottles of molasses, etc.
