Adding salt to water results in a phenomenon called boiling point elevation.
NaCl readily dissolves in water, but unlike water molecules, trying to move dissolved sodium or chlorine ions into the vapour phase requires very large amounts of energy. The boiling point of (pure) water is 100 degree C and at this temperature, the dissolved ions simply remain in solution.
The effect is quite small. Dissolving 60 g of salt in a litre of water only raises the boiling point from 100.0 deg C to 100.5 deg C.

Which of the following does not affect rate of evaporation?a)Wind spee...
Surface Area
- The rate of evaporation is directly proportional to the surface area available for evaporation. A larger surface area allows for more water molecules to escape into the air, increasing the rate of evaporation.
Wind Speed
- Wind speed plays a significant role in the rate of evaporation. High wind speeds can help carry away the water vapor molecules that have evaporated, creating a lower concentration of water in the air and allowing for more evaporation to occur.
Temperature
- Temperature is a crucial factor affecting the rate of evaporation. Higher temperatures provide more energy to water molecules, causing them to move faster and escape into the air more rapidly, increasing the rate of evaporation.
Insoluble Heavy Impurities
- Insoluble heavy impurities do not affect the rate of evaporation. The presence of these impurities in the water may affect its purity or appearance but does not impact the physical process of evaporation itself. The rate of evaporation is primarily influenced by factors such as surface area, wind speed, and temperature.
