Question

11. Evaporation of water increases under the conditions:
(a) increase in temperature, decrease in surface area,
(b)increase in surface area,rise in temperature.
(4) decrease in temperature, increase in surface area.
12. Which of the liquids evaporate faster?
(a) Liquid having weak intermolecular forces.
(b) Liquids having strong intermolecular forces.​

Answer 1

Answer:

1. Increase in surface area and rise in temperature

2.liquids having weak intermolecular force

Explanation:

Answer 2

Evaporation means change of state from liquid to gas at any temperature. For phase change, energy must be supplied to break the force of attraction between the molecules and increase in temperature is a result of providing heat. So, increase in temperature and surface area for more conversion per unit time increases rate of Evaporation.
