Answer:
Camphor dissappears if kept in air for a few days because camphor is sublime. it turns into gaseous form without turning into a liquid. it turns into its gas form and is thus no longer visible to the eyes
On humid days, when the air is already saturated with water, sweat evaporates more slowly. This explains why it feels so much hotter in high humidity. When relative humidity reaches a high enough level, the body's natural cooling system simply can't work. Sweat evaporates very slowly, if at all, and the body heats up.
Water seeps out through them and evaporates from the surface of the pot. The energy needed for evaporation is taken from the water kept in the earthen pot. As a result, water kept in earthen pot become cool.
