Gas in a closed solid container obeys the law of Amonton.
Amontons's law states that the pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume remain constant. Gas filled in a closed solid container obeys the Amontons's law.
In a closed solid container, the volume does not change as the temperature of the inside environment increases because there is no space for the gas molecules to expand so we can conclude that due to solid structure of the container, the pressure of the gas molecules does not change the volume of the gas.
<em>As volume decreases, the pressure increases. In this case, squeezing the bottle reduces the volume. However, the volume in which the particles bounce around in is decreasing, therefore the number of collisions between the particles and the inner surface of the water bottle increases. The pressure the gas exerts on the inside of the bottle is greater than the pressure exerted on the bottle by the outside air. When the hot air is cooled, the gas particles slow down and the volume of the gas decreases.</em>
This ability of water is called a capillary action. This ability is exhibited by liquids where they flow in tubes without any assistance. This happens due to adhesion, cohesion and surface tension.
The best method for separating two liquids in a mixture is distillation among the choices. Distillation separates liquids in terms of their volatility. Evaporation separates liquid from solid. This also applies for filtration which applies porous media for separation. Sorting is applied for two or more different kinds of solids. Answer is distillation.
