If a liquid is sealed in a container and kept at constant temperature, how does its vapor pressure change over time? With increase in temperature the particles of liquid at surface get required kinetic energy to overcome the force of attraction and escape in air quickly. Was this answer helpful? Answer (1 of 16): To evaporate, water molecules from the water surface must possess enough energy to overcome the intermolecular attraction forces between neighbouring molecules, allowing them to break free and become a gas. While putting clothes for drying, we spread them out. Humidity: Humidity is the amount of water vapour present . Humidity, or water vapor content of the air, also has an effect on evaporation.

This framework forms part of a series of measures adopted by the Bank to enable innovative application of technology in the financial sector. Rate of evaporation increases with increase in surface area by spreading the clothes. During evaporation, molecules near the surface of the liquid acquire enough kinetic energy to overcome the attractive forces of other molecules and escape into the atmosphere. The rate of evaporation increases with an increase in temperature because warmer air is capable of holding more air. All the evaporation requires heat, because it take energy to break a water molecule away from the stuff it's stuck to.

Higher evaporation and precipitation rates are not evenly distributed around the world. Rate of evaporation is directly proportional to the change in temperature. Multiple guess 81 terms. Relative Humidity Relative humidity increases during the wet season. Lower pressure on open surface of the liquid results in the higher rate of evaporation. Disclaimer|Personal Data (Privacy) Policy|Copyright, Sino Group|Sino Residential|Sino Malls|Sino Industrial. Under similar conditions, the ocean water evaporates about 5 per cent more slowly than the fresh water. Relative humidity (RH) is equal to the condensation rate divided by the evaporation rate, multiplied by 100 percent. Evaporation: As the humidity increase, the rate of evaporation decreases. More and more molecules come to the surface of liquid hence the rate of evaporation will increase with an increase in temperature. age water temperature of 70 F., the increased evaporation rate due to wind was about 0.5 per cent a day for each mile of wind. Warmer the evaporating surface, higher the rate of evaporation. Water can evaporate just above freezing; however, the process is faster in warmer temperatures.
