Case morning: a thermodynamics problem
Thread Content
In the morning, there was a thermodynamics problem involving finding the maximum pressure and thereby the maximum temperature. I can’t remember exactly; was the gas law used? The final answer was something like -85.2
I remember it seems to be around -85.x
I’m also -85.2°. I just don’t know if using the ideal gas law will result in an error. I’m not sure about this one
It seems to be 16 g of hydrogen at 5 MPa; what is the temperature?
Check out the great posts below; all the questions are from the actual exam: http://bbs.hcbbs.com/thread-1060251-1-1.html. For information on hydrogen in gas cylinders: http://bbs.hcbbs.com/forum-22-2.html. There’s also information on raising the temperature of cooling water to 20°C, and more.
It should be the ideal gas law
I also use the ideal gas equation, but it seems wrong to apply this equation at 5 MPa; however, no other parameters are given in the problem, such as the compressibility factor.
