    Entropy Silver
AI Thread Summary
The discussion centers on the relatively similar change in entropy values for 1 mol of N2, silver, and water, with specific values provided for each substance. Participants note that while the values appear distinct, they align with textbook answers, suggesting a possible consistency in thermodynamic behavior among these substances. The inclusion of mercury is acknowledged but deemed less significant to the main inquiry. The conversation emphasizes the need for a deeper understanding of the factors influencing entropy changes across different materials. Overall, the thread seeks clarity on the underlying reasons for the close entropy values despite apparent differences.

Can someone explain to me why the change in entropy for 1 mol of N2, silver, and water are all relatively close together? The values of the change in S I respectively are S=72.8060J/K, 102.1817J/K, 86.6032J/K, 108.8686J/K.

Yea to me they don't even look close together but they agree with the book's answer (assuming the book is correct).

N2, silver and H2O are the three substances but you have four values for S
 
Opps I forgot to mention Mercury is in there also. But that's not too important. I would like to know why their delta S are all "close"
 

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...
