Why do basements/cellars tend to attract mold and mildew so much?
A cellar is usually colder then the outside as it is kept dark and surrounded by cold dirt. Humidity is based on not only the amount of water in the air but also the temperature of the air. So when ai
Why does fusion release energy?
Ummm, the energy released during fission is not, like, stored inside the nucleus of the atom, but it's actually (some part of) the nuclear mass, which gets transformed into energy. This is called as "
Why do flight fares change all the time instead of having fixed fares like buses and trains?
Trains and busses for public transportation are regulated and subsidized by the government. The city or state will have a transit authority or department of transportation negotiate and partially subs
Why did we nuke Hiroshima and Nagasaki instead of hitting Japan’s military bases?
> I don't see why hundreds of thousands of people had to pay the price for the actions of their government. In a sense, that's why we did it. The Japanese were basically too stubborn to give up, an
Why land masses who are somewhat close to Antarctica such as New Zealand don’t get cold?
New Zealand is somewhat close to Antarctica in roughly the same way as Paris is somewhat close to the Arctic, and has a broadly similar climate.
Why is there sometimes a slightly enjoyable “shiver” after urinating?

Why do tea bags say ‘Do Not Microwave’?

Why is tinfoil (aluminum foil) so heat resistant?
Heat resistent in what way? If you refer to "Why doesn't it melt", simply because it's melting point is incredibly high, much higher than your grill can produce ((660.32 °C, 1220.58 °F). If you are
Why would Assad’s regime use chemical weapons, as opposed to conventional ones, which don’t generate anywhere near the same international uproar and are presumably equally lethal, albeit less horri…
> presumably equally lethal This is pretty much why. Chemical weapons tend to have very high human casualties while being able to minimise damage to infrastructure. To achieve the same effect with
Why do we still use propeller planes in the Air Force?
Turboprop engines are far more fuel efficient than jet engines, and more reliable in unimproved areas with lots of dust, sand, grass, and rocks. So they are the engine of choice in applications where
