What is the difference between condensation and evaporation?


Quick Answer

Evaporation happens when liquid turns into gas whereas condensation occurs when gas changes to liquid. The higher the temperature of the liquid, the higher the rate of evaporation becomes. In contrast, the condensation rate rises when the temperature of gas lowers.

Gas and liquid both possess particles with different energies. The water molecules in liquid water are kept close together by attractive forces. However, their movement is not restricted, and they can move around each other. The molecules also possess thermal energy, enabling them to vibrate strongly sometimes and causing them to exit into the air and turn into vapor.

Water molecules in the atmosphere simultaneously move back to the water surface and become part of the liquid. The relative humidity lowers below 100 percent when the water molecule concentration in the air becomes less than the greatest concentration the air can maintain. This results in evaporation, where there’s a higher number of molecules that jump from the liquid to the atmosphere than the number that transfers from the air to the water. This process is reversed for condensation, as it occurs when the air contains more water vapor than it can keep, and the number of water molecules going to the water from the air is higher than the number of molecules entering the air from the water.
