General Science / Is there a solution to steamy windows?

« on: 07/11/2010 09:44:50 »

Every morning, at this time of year, my windows are dripping with water. I think this must be because the outside of the glass is so cold, and the inside is warmer, hence the condensation. This water runs down the windows and makes everything in the vicinity wet. Having  a bath or shower just adds further steamy windows.

Is there a solution to this?

And, in science terms, why are the windows not wet in the colder weeks of winter? The temperature difference between in and out is greater, so there should be more condensation, shouldn't there? Not so: if it's snowing outside, the windows are completely dry. Why?

Why do some wading birds have yellow legs? There must be a good reason.
