One factor is temperature. b. Another factor is the molecular weight of the solute. 2) Why is drinking seawater a sure way to shorten your survival if you are stranded on a desert island? Drinking seawater will most definitely shorten your survival because seawater is very high in salinity. Since a lot of salt has just entered the body, water will start diffusing from cells to dilute and excrete this sudden intake of salt. This will leave you very dehydrated and increases your risk of death 3) Will there be net movement of water molecules between two isotonic solutions separated by a selectively permeable membrane?
