Everyday Phenomena
Explanations for events observed at home, on the street, in the kitchen, at work and during travel.
Why does water boil sooner at altitude but food takes longer to cook?
At altitude, lower atmospheric pressure reduces the boiling point of water. It may boil sooner, but it boils cooler - and this slows down the cooking process.

Where does the air conditioning water come from — and when is dripping normal or a sign of a problem?
The water in air conditioning comes from the humidity in the air itself. Understand condensation in the evaporator and how to differentiate normal drain from an internal leak.

Why a fan cools you without cooling the room — and what humidity changes
The fan does not lower the room temperature: it accelerates the loss of body heat. Humidity interferes because it limits the evaporation of sweat.
