Question: What Are The Factors Affecting Evaporation Class 9?

What increases rate of evaporation?

When water temperature increases (right), the rate of evaporation also increases.

In turn, the amount of water vapor in the “air space” above the water increases..

What is evaporation give examples?

Evaporation is defined as the process of a liquid changing into a gas. An example of evaporation is water turning into steam.

What is evaporation and factors affecting evaporation?

Evaporation takes place when a liquid turns into a gas. Evaporation is also known as vaporization. Vaporization usually happens on the surface of the water. … Vaporization also depends on factors like temperature, humidity, pressure, wind speed, and surface area.

What are 3 factors that affect evaporation?

The evaporation rate is an important factor that influences the effect of evaporative cooling of permeable pavements. It is determined by a complex system of factors, such as air temperature, relative humidity, water temperature, moisture content, air void content, size, and structure.

What is evaporation Class 9?

The process of liquid changing into vapours even below its boiling point is called as evaporation. … Thus,the fast moving particles of a liquid are constantly escaping from the liquid to form vapour. Factors affecting evaporation. 1)Temperature. The rate of evaporation increases on increasing temperature of the liquid.

What is evaporation very short answer?

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.

What is evaporation explain it?

Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. … Heat from the sun, or solar energy, powers the evaporation process.

How does temperature affect evaporation?

Evaporation rates are higher at higher temperatures because as temperature increases, the amount of energy necessary for evaporation decreases. … Humidity, or water vapor content of the air, also has an effect on evaporation. The lower the relative humidity, the drier the air, and the higher the evaporation rate.

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.

What is evaporation in simple words?

Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils; in particular, the process by which liquid water enters the atmosphere as water vapour.

What are the 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 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.

What are some examples of evaporation?

13 Everyday Life Examples of EvaporationDrying Clothes under The Sun. One of the most common real-life examples of evaporation is drying of clothes under the sun. … Ironing of Clothes. … Cooling Down of Hot Tea and Other Hot Liquids. … Wet Floors. … Melting of Ice Cubes. … Preparation of Common Salt. … Evaporation of Nail Paint Remover. … Drying of Wet Hair.More items…
