Q1.
If the humidity in Delhi is at 52% while in Kochi it is 84%, in which of the two places are wet clothes likely to dry faster? And where are you likely to sweat more, assuming the temperature is the same in both places?
Answer
Wet clothes dry faster in Delhi, and you will sweat more in Kochi.
Delhi: 52% relative humidity → the air is only about half ‘full’ → plenty of room for more vapour → fast evaporation → clothes dry quickly
Kochi: 84% relative humidity → the air is nearly saturated → little room left → slow evaporation → clothes stay damp for hours
Kochi: 84% relative humidity → the air is nearly saturated → little room left → slow evaporation → clothes stay damp for hours
Why you sweat more in Kochi: You do not actually produce much more sweat — it simply does not evaporate. Sweat cools you only when it turns into vapour. In Kochi's 84% air it cannot evaporate fast enough, so it stays on your skin, your body stays hot and keeps producing more. In Delhi's 52% air the same sweat evaporates quickly, carries heat away, and your skin feels dry. That is exactly why 29°C in coastal Kochi feels far more uncomfortable than 29°C in Delhi.
Tip: Notice that the question says “assuming the temperature is the same in both places”. That is essential — if the temperatures differed, you could not separate the effect of humidity from the effect of heat.
