"The forces of attraction and the volume of the molecules" (as opposed to the volume of the container the gas is in).
Most definitely gravity. Gravity is what makes things go up and or down
<span>If energy is released, the reaction is exothermic. If energy is absorbed, the reaction is endothermic. Since heat is being absorbed in this reaction (to break down H2O into H2 and O), the reaction is endothermic.</span>
25 gigaseconds is equal to 2,500,000,000,000 centiseconds

The less molecules of a substance in a sample, the lesser the concentration. We are often concerned about analytically determining the concentration of a substance using diverse analytical methods in chemistry.
