Daltons law of partial pressure (article) - Khan Academy

Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the partial pressures of its components: where the partial pressure of each gas is the pressure that the gas would exert if it was the only gas in the container. That is because we assume there are no attractive forces between the gases.

How Alcohol Works HowStuffWorks

Dec 21, 2000 The type of alcohol found in alcoholic beverages is ethyl alcohol or ethanol. The molecular structure of ethanol is C2H6O. It can also be written as CH3CH2OH or C2H5OH. In this structure, C is carbon, H is hydrogen, O is oxygen. The OH (O-H) group on the molecule is what gives it the specific chemical properties of an alcohol.

Fractional distillation - Energy Education

Fractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels.

The difference between simple and fractional distillation is the number of times that the liquid is vaporized and condensed.

How Does the Particle Model of Matter Explain Dissolving?

The particle model of matter states that the matter we can see is made up of a huge number of very small, identical particles. When you dissolve a solid in water, these molecules still exist. However, they separate from their intermolecular bonds and become microscopic in the water. The extent to which this dissolution happens is called solubility.
