Cooling down a container in outer space - Physics Stack Exchange By contrast the container in space can only cool by black body radiation, and obviously it will cool down more slowly You can calculate the cooling in space using the Stefan-Boltzmann law assuming you know the emissivity (if you paint the container black the emissivity will be close to unity)
thermodynamics - Cooling a satellite - Physics Stack Exchange 2 There are several ways for thermal management (cooling and heating) of a satellite and in general a spacecraft Heat can be removed from the spacecraft in space by radiation only, assuming that the spacecraft is outside the atmosphere of a planet such as the Earth or Titan (largest moon of Saturn) or Mars
Why do things cool down? - Physics Stack Exchange In space, the objects around you (mostly interstellar medium) is cooler than you so you radiate more heat away from you into them than they radiate toward you If you were thrown out into space, but very near a star, you might receive more heat from the star more than you could radiate away into space, and you would heat up rather than cooling
What kind of cooling mechanism could be used in outer space? The International Space Station where astronauts spend years needs a long-term solution, a cooling system that was developed by Boeing and contains many components In some of them, ammonia is used There are lots of engineering issues but the things work when the dust is settled and bugs are fixed
thermodynamics - How can ambient cooling cool a system to below the . . . Assuming the cooling system is just a radiator, water and a pump then you can't cool the fluid below the ambient temperature of the radiator A refrigerator manages this by compressing the fluid in the cooling circuit, extracting the excess heat and then expanding it to make it colder If your system uses a phase change, a compressible fluid or a peltier stack it is a refrigerator edit
How fast would body temperature go down in space? 11 What would be the rate of temperature loss for an average sized human in space without a suit? A human generates about 100 watt at rest But how can we use that to calculate how fast the temperature will go down? Also how much heat would be absorbed by the sun? Assume the person is somewhere between the earth and the moon
How can space be cold? Its a vacuum? - Physics Stack Exchange Closed 10 years ago I was reading that space is very cold and also it is a vacuum, and so my question is quite simple, if temperature is the "jiggling" of atoms and molecules and heat is distributed through jiggling particles passing the energy by hitting other atoms thus cooling or getting hotter
Why is cooling much harder than heating? - Physics Stack Exchange 13 You could blame the laws of thermodynamics and say that cooling is much harder in our universe because of them However, since we're in a dark energy-dominated universe that's expanding and cooling, it seems as though cooling is generally easier for the universe on the largest scales
