Evaporation | MCQs

Explanation

Transpiration is the process by which plants lose internal water in the form of water vapor through aerial parts such as leaves, stems, and flowers.

This process occurs mainly through small openings called stomata.

Explanation

The rate of evaporation can be increased by:

• Decreasing atmospheric pressure
• Increasing temperature
• Decreasing humidity
• Increasing the surface area of the liquid

Explanation

Evaporation occurs when molecules on a liquid's surface gain enough energy to escape into the air, and this can happen at any temperature, not just at boiling point.

It's a slow process at lower temperatures, but faster at higher temperatures.

Explanation

Evaporation is the process by which molecules escape from the surface of a liquid to become vapor, even if the liquid is below its boiling point.

This occurs when some molecules have enough energy to break free from the surface tension of the liquid and turn into vapor.

Key Points:

• Boiling occurs when a liquid is heated to its boiling point, causing bubbles to form and rise to the surface.
• Condensation is the process by which vapor is converted back into a liquid.
• Convection is the transfer of heat through the movement of fluids.

Explanation

• In the evaporation process, liquid molecules gain energy and move faster.
• It allowing them to escape from the surface of the liquid into the surrounding air.
• This occurs when the molecules have enough energy to overcome the intermolecular forces holding them to the surface.

Explanation

• Transpiration is the process by which water is transported through the plant and evaporates from the aerial parts.
• Such as leaves, stems, and flowers, primarily through small openings called stomata.

Explanation

• When water evaporates, it changes from a liquid to a gas.
• This gaseous state is called water vapor.
