What happen during condensation?

Condensation is the process by which water vapor in the air is changed into liquid water. The phase change that accompanies water as it moves between its vapor, liquid, and solid form is exhibited in the arrangement of water molecules.

When water is condensed its volume increases?

When water is condensed its volume increases. Till reaching the temperature of approximately 4 degrees Celsius, the volume of it contracts while cooling the water.

Does heat increase or decrease in condensation?

condensation, deposition of a liquid or a solid from its vapour, generally upon a surface that is cooler than the adjacent gas. Heat is released when a vapour condenses. Unless this heat is removed, the surface temperature will increase until it is equal to that of the surrounding vapour.

Does pressure increase or decrease during condensation?

The rate of condensation depends mainly on the vapor pressure in the space above the liquid surface. The vapor pressure increases as the concentration of water vapor in the space above the liquid increases.

What are the factors affecting condensation?

The factors governing condensation

• The water vapour content of the air.
• Inside room temperature.
• Outside temperature.
• Internal and external temperature variation.

What phase change happens during condensation?

During condensation, a substance is changed from the gaseous to the liquid state of matter. Vaporization, which is more often referred to as “boiling,” is the complementary process in which a chemical is converted from the liquid state of matter to a gaseous physical form.

Does volume decrease in condensation?

The molecules are very close (condensation occurs) and there is a dramatic decrease in volume, as seen in Figure 1. The substance changes from a gas to a liquid. When a liquid is cooled to even lower temperatures, it becomes a solid. High pressure may also cause a gas to change phase to a liquid.

How does condensation work on glass?

Condensation on Glass When the hot air comes in contact with the cold glass, heat is transferred from the hot air to the cold glass. The loss of heat in the surrounding air causes the water vapor by the glass to lose energy. Once energy is lost, the water vapor condenses into liquid on the glass.

How do you increase condensation?

Making water vapor colder increases the rate of condensation. Increasing the concentration of water vapor in the air increases the rate of condensation.

Does kinetic energy increase or decrease during condensation?

Condensation is the change of state from a gas to a liquid. Liquid molecules that have this certain threshold kinetic energy escape the surface and become vapor. As a result, the liquid molecules that remain now have lower kinetic energy. As evaporation occurs, the temperature of the remaining liquid decreases.

How does condensation of a gas occur?

Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. In evaporation, matter changes from a liquid to a gas. In condensation, matter changes from a gas to a liquid.

Does the viscosity of a liquid decrease during condensation?

As you mentioned during condensation, the answer is no, temperature will remain constant. Also do note that during phase change there is no change in temperature. Let it be any phase change. Why does the viscosity of liquids decrease with increasing temperature, while that of gases increases with increasing temperature?

How does condensation increase the temperature of surroundings?

In condensation vapours combine to form liquid hence it loses its energy and produces heat which ultimately increases the temperature of the surroundings.

Does temperature change during condensation and phase change?

It is interesting to note that ‘no temperature change occurs during condensation’. As you mentioned during condensation, the answer is no, temperature will remain constant. Also do note that during phase change there is no change in temperature. Let it be any phase change.

What is the formula for the rate of condensation?

The rate of condensation (R) depends on the concentration of gas molecules (reactants), and it’s defined as: R = k [Gas]
