Question: Which Factor Does Not Affect Evaporation?

Which of the following does not affect evaporation?

With the increase in temperature, rate of evaporation increases and with the decrease in temperature, it decreases.

But rate of evaporation doesn’t gets affected by insoluble impurities, because these are going to stay as it is but the liquid will evaporate.


What are factors that affect evaporation?

Factors That Affect the Rate of Evaporationtemperature of the liquid. A cup of hot water will evaporate more quickly than a cup of cold surface area of the liquid. … presence or absence of other substances in the liquid. … air movement. … concentration of the evaporating substance in the air.

How fast does evaporation happen?

There is no specific time period of evaporation it depands upon the surface area of contact, temperature of liquid (evaporation is faster at high temperatures), humidity of air, purity of water ( more purity causes more evaporation). could you define (0.089 + 0.0782) what these values represents?? 3 to 4 weeks.

What is evaporation with diagram?

Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.

Does evaporation depend on temperature?

The rate of evaporation depends on the temperature difference between the evaporating surface and the air, the relative humidity, and wind.

Which factor does not affect rate of evaporation?

The rate of evaporation does not depend on the type of particles because it completely depends upon the surface area of the liquid, if surface area is large evaporation will be maximum.

What are the factors affecting evaporation Class 9?

EvaporationTemperature. The rate of evaporation increases on increasing temperature of the liquid. … Surface Area. The rate of evaporation increases on increasing the surface area of the liquid. … Humidity of air. The amount of water vapours present in air is called humidity. … Wind Speed.

Does pressure affect rate of evaporation?

Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor. … Temperature, of course, affects how quickly evaporation happens.

Does wind speed affect evaporation rate?

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.

What increases the rate of evaporation?

When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.

Why does the rate of evaporation occur?

A substance that has a larger surface area will evaporate faster, as there are more surface molecules per unit of volume that are potentially able to escape. the higher the temperature of the substance the greater the kinetic energy of the molecules at its surface and therefore the faster the rate of their evaporation.

Does higher vapor pressure mean faster evaporation?

The greater the pressure it exerts, the weaker the intermolecular forces between molecules in its liquid state; the more volatile the liquid; the lower the boiling point and the faster its evaporation rate. … The higher the vapor pressure of a material at a given temperature, the lower the boiling point.

What is rate of evaporation?

Safety Data Sheets: An evaporation rate is the rate at which a material will vaporize (evaporate, change from liquid to vapor) compared to the rate of vaporization of a specific known material. This quantity is a ratio, therefore it is unitless.

At what temperature does evaporation occur?

Why evaporation occurs Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point.
