Salt does not directly affect the evaporation of water. However, the evaporation habits, temperatures and movement of certain areas of saltwater bodies can affect the salinity, or salt level, of those bodies of water, re... More »

The major factors influencing evaporation are pool surface area, water and air temperatures, humidity, and wind. Large pools evaporate more water. Differences between air and water temperatures increase evaporation; dry ... More » Science Environmental Science

Water evaporates faster without salt. For example, when the sea's salinity increases, the evaporation rate is slower. Salinity refers to the amount of salt in water. More »

Salt melts ice by lowering the melting point of water. Pure water changes into ice at 32 degrees Fahrenheit. When salt is added to water, the melting point drops. If the temperature is above the new melting point, then t... More »

Salt added to water in a cup makes an egg float because the saltwater's density is greater than the egg's density. Density is a substance's mass divided by its volume. When sufficient salt is added to tap water, the mass... More » Science Chemistry

Salt increases blood pressure in some people, because its component sodium causes the body to retain excess water to eliminate the salt, explains Cleveland Clinic. The extra water adds stress on the heart and arteries, l... More » Health Nutrition & Diets

Wind increases the rate of evaporation by removing air already laden with water vapor from above the water. The rate of evaporation depends, in part, on the existing level of water vapor in the surrounding air, since wat... More »
