i am doing an arts n' crafts project in the summer and i need ideas that wont cost me a lot.like not more than 3 bux a child because otherwise i wont make money.does anyone have ideas.please?
here on Earth we have an atmosphere that has a certain temperature and a surface that absorbs the sun's raysBut in a vacuum there's nothing to measure the temperature of Oh you can measure the background microwave radiation, but you get an answer of about -450 degrees farenheitIf you put an object out in space it will heat up to a certain temp depending on how much sunlight is hitting itIn the shady side of the object it will tend to get very cold, as the heat of the object will tend to radiate out into deeep space, at -450FOn the sunny side it will warm upIf the object is small or made of something very conductive to heat, the temperature on the hot and cold sides will tend to averge outIf it's made of very insulating stuff, like moon rocks, the temperature difference will be greater On the Moon the dark parts are down at -200F or so, the parts in the sunlight are at +200 or thereaboutsOut by Pluto the sunlight is much weaker, so the sunny side of objects does not get very warm at all, maybe -150F?
The temperature of anything is a measure of the average energy of its atoms/moleculesA perfect vacuum, therefore, has no temperatureBut even the rarest amount of gas has a temperature defined by its atom/molecular motion, and that depends on the environmentEnergy can be transferred to an object via conduction (contact), convection (mixing), or radiationIn space, only radiation plays role so temperature is based on nearby radiating objects (like the Sun or a Star) The background radiation of space also supplies a small amount of energy equivalent to 2.73 Kelvin.
