The addition of the two molecules typically proceeds in a step-wise fashion to the addition product, usually in equilibrium, and with loss of a water molecule (hence the name condensation).

Ice is less dense than water. When liquid water freezes, it’s particles expands i.e increases in volume. Hence, it becomes less dense than water. This causes an iceberg to float on water because it has a lesser density compared to the liquid water caused by an expansion of its particles.

The process of splitting the bond between monomers is called hydrolysis. Hydrolysis means “to break with water”. Since a water molecule was lost during dehydration synthesis, hydrolysis brings the water back.

A condensation reaction occurs when two molecules join to form a larger molecule and release a smaller molecule(s) in the process. The smaller molecule lost in the reaction is often water, but it can also be methanol, hydrogen chloride, acetic acid or several other molecules.

Dehydration synthesis is the process of joining two molecules, or compounds, together following the removal of water. During a condensation reaction, two molecules are condensed and water is lost to form a large molecule. This is the same exact process that occurs during a dehydration synthesis.

Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.

What causes condensation? When warm, moist air comes into contact with cooler surfaces, the excess moisture in the air condenses. That’s because the cooled air next to the cool surface can’t hold as much moisture as the warmer surrounding air.

They include:

• temperature of the liquid. A cup of hot water will evaporate more quickly than a cup of cold water.
• exposed surface area of the liquid.
• presence or absence of other substances in the liquid.
• air movement.
• concentration of the evaporating substance in the air.

Due to high humidity the temperature of the surrounding decrease along with the rate of evaporation. This is because evaporation is a surface phenomenon and with an increase in humidity, the amount of water vapour increases in the atmosphere thus there is not enough space for new water vapour.

As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.

The higher the temperature of substance or liquid, the greater is the kinetic energy of the molecules at its surface, and therefore the faster the rate of evaporation. If the air is saturated with great amount of water causing high humidity, it causes low capacity for the evaporating substance.

When gas molecules transfer their energy to something cooler, they slow down and their attractions cause them to bond to become a liquid. Making water vapor colder increases the rate of condensation. Increasing the concentration of water vapor in the air increases the rate of condensation.

When the speed of wind increases, the particles of water vapour move away with the wind, decreasing the amount of water vapour in the surroundings. This increases the rate of evaporation of water.

Answer: Evaporation increases with the increase in wind speed. Vapour particles move away when the speed of wind increases. This leads to an increase in the amount of water vapour in the atmosphere.

Increasing the wind speed increases the first stage evaporation rate and decreases the transition time between two evaporative stages (soil water flow to vapor diffusion controlled) at low velocity values; then, at high wind speeds the evaporation rate becomes less dependent on the wind speed.
