Question

explain two example from our daily life where we feel the effect of cooling due to evaporation

Answer 1

1) Hot tea gets cool over time due to evaporation - hot molecules on the surface gets evaporated taking away heat with them.
2) Wet clothes dry in sun due to evaporation - the water in wet clothes takes heat energy from sun and gets evaporated.
3) Evaporation of perspiration from body - Sweat on our body evaporates taking away heat from our body
4) Drying of a mopped floor
5) Drying of wet hair after some time
6) drying up of water bodies like lakes and rivers
7) Evaporation of water from earthen pots
8) Evaporation of water sprinkled on ground or roof top
9) Evaporation of nail paint remover when applied on nails - acetone in nail paint remover takes heat from our body and evaporates.
10) Preparation of common salt from sea water by evaporation

Hope this helps you!!!

Answer 2

Answer:

Water molecules transform from liquid to gases or vapors on the surface of liquids during the process of evaporation.

Explanation:

The two examples from our daily life where we feel the effect of cooling due to evaporation is as follows below:

1. Airing out clothing in the sun

• The process of drying garments in the sun is one of the most prevalent instances of evaporation in everyday life.
• When wet garments are exposed to the sun, they become heated up, which causes the water molecules to evaporate, drying the clothes.
• The water vapors in the fabric of the clothing are evaporated by the hot iron, which aids in effectively ironing the clothing.

2. Melting of Ice Cubes

• We've all probably seen that when ice cubes are removed from the refrigerator to be used in beverages, they eventually melt and take the shape of the liquid.
• It changes from a solid state to a liquid one.
• The water evaporates outside the refrigerator as a result of the higher temperature, which changes the form of the ice cubes.

Hence, the two examples of evaporation from our daily life is explained above.
