People had asked this many times and that is why they came up with methods and standards that will answer these type of questions. You can look it up in the NIST or the National Institute for Standards and Technology.
It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.
For adiabatic process,
PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.
where gamma = Cp
------
Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.
Value of Gamma will be given in question.
Hope this helps!
Answer:
The part of the earth’s surface where, at temperatures below 32°F (0°C), the water is frozen solid. Even a small pond while frozen over during the winter is part of the cryosphere, but cryosphere refers more often to large regions covered in snow and ice for much or all of the year, as the ice sheets of Antarctica and Greenland, glaciers, icebergs, and expanses of permafrost, all of which are especially sensitive to global shifts in climate:
Explanation:
Answer:
I believe the answer is B.
Explanation:
I have never heard of it meaning the coldest point in outer space or freezing point of "pure" water at sea level. As for C, substances have a different points where the molecules stop moving. So the answer that makes the most sense is B.
