You want to wear your favourite shirt to a
party, but the problem is that it is still wet after a wash. What steps would you take to dry it faster?
Answer:- Wet cloths dried up because of evaporation. The rate of evaporation increases with the increase in
temperature, surface area and wind speed.
Hence, keeping the conditions to increase the rate of evaporation in mind, following steps should be taken to get the favourite shirt dried up quickly-
(a) We shirt should be spread up on the wire. This will increase the surface area of wet shirt which will increase the rate of evaporation.
(b) Speedy wind should be supplied to the shirt using a fan which will increase the rate of evaporation.
(c) If it is a day time, arrange the above combination in the sun, so that increase in temperature would increase the rate of evaporation.
(d) If it is not a day time, a hot iron can be used also before hanging the shirt on a wire.
