AI Thread Summary
The discussion focuses on calculating the total change in entropy for a thermal conduction system involving a metal wire connected to two heat reservoirs at different temperatures. The relevant equation used is dS = dQ / T, where dQ is the heat transferred. The participant initially doubts their calculation but ultimately confirms that their approach is correct, yielding an entropy change of 1.72 J/K. The problem is part of a larger homework assignment, and the participant expresses concern about its complexity relative to its point value. The conversation highlights the importance of understanding entropy in thermal systems.

Homework Statement


Each end of a metal wire is in thermal contact with a different heat reservoir.
Reservoir 1 is at a temperature of 752 K, and reservoir 2 is at a temperature of
345 K. Compute the total change in entropy that occurs from the conduction of
1096 J of heat through the wire.


Homework Equations


dS = dQ / T


The Attempt at a Solution


I'm really unsure how to solve this question. Would I do something like this:

-1096/752 + 1096/345 =
-1.457 + 3.177 = 1.72 J/K

Or am I totally off base on this one?

I am not sure why you are unsure. You have the right equation and you have the right answer.

Wow, okay... Thanks for the reassurance then! :)

The question has a point value of 6 points out of a 25 point homework assignment, so I thought there might be more to it than that, but apparently I thought wrong.
 
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...
