    Hawking radiation and BH evaporation time

    I don't know a lot about this topic so corrections are solicited. My understanding is that black holes evaporate by Hawking radiation. Hawking radiation, by my reading, occurs when a pair of virtual particles emerges very close to but just outside the event horizon of the black hole. When...

    Do pH levels carry on thorugh evaporation?

    I need to know: In a closed system sealed off from outside air, if water from a mass of basic water evaporates, will the pH of the air be affected? If so, when the air condenses, how wil the pH of soil in the closed system be affected? Thanks for the help.

    How can you create a large NaCl crystal using evaporation techniques?

    How would someone go about creating a large NaCl crystal? Is there a special evaporation technique involved with a saturated solution? As a side question why is sugar in crystal form? I mean isn't sugar a covalently bonded molecule?

    What factors affect the evaporation speed of liquids?

    I'd like to know if there's any law/formula that allows you to calculate the evaporation speed of a liquid at a precise temperature, pressure, with a precise surface. Which physical parameters of the substance should i know? Thank You! Ciao! Andrea

    Factors involved in water evaporation?

    Does anyone know the formula that describes the evaporation rate of water? I'm assuming it involves temperature, dew point, relative humidity and other factors. Thanks in advance.
