The evaporation of water increases under the following conditionsa)In...
Explanation:
Introduction:
Evaporation is the process by which a liquid substance changes into a gaseous state. It occurs when the molecules in a liquid gain enough energy to break free from the liquid and enter the surrounding air. Several factors can affect the rate of evaporation, including surface area, temperature, and the presence of other substances.
Increase in surface area:
- When the surface area of a liquid is increased, more molecules are exposed to the surrounding air, which leads to an increase in the rate of evaporation.
- This happens because the molecules at the surface of the liquid have a higher chance of gaining enough energy to escape into the air.
- Therefore, an increase in surface area will result in an increase in the rate of evaporation.
Rise in temperature:
- Temperature is a measure of the average kinetic energy of the molecules in a substance.
- When the temperature of a liquid is increased, the kinetic energy of the molecules also increases.
- As a result, more molecules will have enough energy to escape from the liquid and enter the gaseous state, increasing the rate of evaporation.
- Therefore, a rise in temperature will result in an increase in the rate of evaporation.
Conclusion:
Based on the above explanations, we can conclude that the correct option is 'B' - Increase in surface area, rise in temperature. Both factors contribute to an increase in the rate of evaporation.

The evaporation of water increases under the following conditionsa)In...
When surface area increases and the temperature rises, evaporation of water also increases, because the area which is exposed to the outer atmosphere is more and increasing the temperature, leads to an increase in the kinetic energy, due to which the rate of evaporation also increases.
