What is fascinating about mercury the planet?
The fact that its daytime and nighttime temperatures vary between -183C and +427C.

Answer : 179 Celsius(Day time) 350 degrees celsius. (Night time) 170 degrees celsius.
Why do white flakes fall from the sides of space shuttles fuel tanks?
These "white flakes" are chips of ice formed from water condensing and freezing on the very cold surface of the cryogenically cooled fuel/oxidizer tank. The fuel is liquid hydrogen, at a temperature of about −253C. The oxidizer is liquid oxygen, at a temperature of about −183C. As water freezes at 0C any water vapor in the air around the tanks rapidly condenses and freezes to a layer of ice on the skin of the tank. At launch a combination of vibrations and air frictions causes this ice to breakup and flake off, producing the white flakes that you saw.
How do you liquefy oxygen?
Liquifying nitrogen works by the refrigeration process done on air: 1)Air is purified and put into a pipe. 2)The air is condensed. Under the high pressure, the gas heats up. 3)The hot gas, still under pressure, is allowed to cool a bit. 4)The gas is released from pressure quickly. Not only does the gas cool, it cools below its original temperature. 5) The resulting gas is put back in to the cycle and the process begins again. Each cycle makes the gas colder. First oxygen drops out of the mix, and liquifies at -183C. Nitrogen liquifies soon after, at about -196C.
Which is the coldes planet?
Planets vary widely in temperature from extremely hot to extremely cold. In our solar system the hottest planet is Venus, with surface temperatures of 850 degrees Fahrenheit while the coldest is Uranus at -371 degrees Fahrenheit.
Which planet is the closest to the sun?
The closest planet to our sun is the planet Mercury, at a distance of 57,909,175 km or 0.387 AU (Astronomical Units).Although Mercury is the closest planet to the sun, it is not the hottest; Venus (the second-closest planet to the Sun) is the hottest planet in our Solar System because Venus' atmosphere is thick with greenhouse gases, trapping and retaining a lot of the Sun's heat (not allowing it to reflect back nor radiate away on Venus' night side) whereas Mercury has almost no atmosphere, and more of the Sun's heat radiates away on Mercury's night side; in fact, Mercury's lack of atmosphere and long night (Mercury only completes a day/night cycle once per every two Mercury-years; a Mercury-year is about 89 Earth-days ... this means years on Mercury pass faster than days) give the planet Mercury a huge variation in temperature, from -183C to 427C.In order, from closest to the sun to furthest out:MercuryVenusEarthMarsJupiterSaturnUranusNeptuneMercury VenusEarth
How is oxygen obtained from air?
It cant be its a natural source and can't be "put in a jar" etc and it cant be seen, its just floating around all the time and can't be captured or extracted from anything. xx - hope this helped!
How is oxygen prepared?
Oxygen can be prepared by decomposition of Hydrogen peroxide(H2O2), catalyzed by Manganese dioxide(MnO2).2 H2O2 ---MnO2---> 2 H2O + O2In addition, electrolysis of water will also produce oxygen at one electrode and hydrogen at the other electrode.
