What causes boiling point elevation?
What causes boiling point elevation? A solvent’s vapor pressure will lower when a solute is added. This happens because of the displacement of solvent molecules by the solute. For the vapor pressure to equal the atmospheric pressure, a higher temperature is required, and a higher boiling point is observed. … What happens during boiling point […]
Why is it important that the cell is semi-permeable?
Why is it important that the cell is semi-permeable? The most important thing about membranes is that they regulate what moves in and out of a cell. The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. What are semipermeable examples? An […]
