Would the Laws of thermodynamics work in space?
« on: 13/01/2015 10:30:02 »
Shee Hong  asked the Naked Scientists:
   
Would the Laws of thermodynamics work in space? What about nuclear fusion? Would it be governed by the laws of thermodynamics if it exists?


What do you think?

Yes. If something is a law of physics then it works anywhere at anytime under all conditions. However the details of a law might imply that certain things can't happen.

Yes.

If what exists?

I find this talk of "being in space" as rather nonsensical if we are not in space where the Hell are we, Do they mean that do the laws of thermodynamics only apply in a gravitational field at least as strong as that of the Earth ?.
I am put in mind of the "Brits" who talk of "going to Europe" as though they where not already there.

When people talk about being in space they're almost always talking about being outside the atmosphere of a planet and in frame of reference in free-fall. You can usually tell if they mean this by the context in which its used. For example; When astronaut is in the international space station they are said to "be in space".

For example; see http://www.nasa.gov/audience/forstudents/dayinthelife/

Have you ever wondered what it would be like to live and work in space? Follow astronauts on the International Space Station in a series of videos as they explain their daily routines. Learn where they sleep, and how they eat, exercise, work and spend free time. Compare life in space with life on Earth.
