As a group, alcohols tend to have relatively low vapor pressure values compared to more volatile solvents such as ether. Vapor pressure, the pressure a liquid produces when evaporating, is directly related to evaporation rates. Lower vapor pressures lead to less evaporation, and thus alcohols tend t......[Read More]

If it was not for hydrostatic equilibrium, stars would simply collapse or explode. Instead, they achieve stability through a natural balance of forces. A star's mass determines how much force is required to achieve this stellar balance. Furthermore, mass and hydrostatic equilibrium also affect the s......[Read More]
