Question 1.
Observe the activities in your house for a day. Identify the activities that involve evaporation. How does understanding the process of evaporation help us in our daily activities?
Answer:
The daily life activities in which the process of evaporation is involved :
(а) Drying wet clothes.
(b) Drying wet floor after moping.
(c) Cooling the room in summer season using cooler.
(d) Feeling cool after sweating.
(e) Storing water in earthen-pot for cooling it naturally.
(f) Also, a hot cup of tea cools down due to evaporation.
After learning and understanding the process of evaporation, we now can analyse that if we want to increase the rate of evaporation for our benefit, then we can change some factors. For example, we can put on the fan on high speed to dry mopped floor. We can pour the tea on plate to cool it faster or blow air over it. Hence, we can use the knowledge of factors affecting to increase or decrease the rate of evaporation for our use.
