Q. Why are white clothes more comfortable in summer than dark or black ones?
A. White clothes are good reflectors and bad absorbers of heat, whereas dark or black clothes are good absorbers of heat. Therefore, white clothes are more comfortable because they do not absorb heat from the sun rays.
A. After a shower, the clouds containing water droplets act like a prism through which the white light is dispersed producing a spectrum.
Q. Why are air coolers less effective during the rainy season?
A. During the rainy reason, the atmosphere air is saturated with moisture. Therefore, the process of evaporation of water from the moist pads of the cooler slows down thereby not cooling the air blown out from the cooler.
