AI Thread Summary
The discussion focuses on analyzing the thermodynamic properties of a monoatomic gas undergoing a multi-step process consisting of isothermal expansion, constant pressure, and constant volume changes. Key calculations include determining the work done by the gas, heat yielded and received, and the overall efficiency of the process. Participants emphasize the importance of treating each step separately and keeping track of heat (Q) and work (W) for accurate results. Specific relationships, such as Pa=5Pc and Vb=5Vc, are noted for calculations. The efficiency of this process is also compared to that of a Carnot machine operating under the same temperature variations.

Homework Statement



I need help with this question here.
Its thermodynamics.
I don't know the enunciate for sure, but I explain it
1 mol of a monoatomic gas passes for the processes:


A->B->C

AB is a isothermal expansion process
BC is a constant pressure process(Loses volume)
CA is a constant volume process (gains pressure)

Pa=5Pc and Vb=5Vc
The answer is in Terms of Pc and Vc

a) The liquid work that the gas.
b) how mush heat does the gas yields?
c)hot much heat does the gas receives?
d) the efficiency of the process
e) compare its efficiency to a carnot machine with the same temperature variations.


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
anyone?
 
You need to treat each step in the process separately ... keep track of Q and W and Delta(I.E.) for each, so 9 entries.
The bookkeeping is not as bad as it sounds ... isotherm Delta I.E. = 0, for example, and constant Volume compression has W = 0 .
You should know formula for W during constant pressure - Look-up formulas for isotherm.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
