Is Energy or Entropy Conserved?

Start date Oct 20, 2008

AI Thread Summary

Energy is conserved according to the laws of thermodynamics, while entropy tends to increase in isolated systems, indicating it is not conserved. Heat is not a conserved quantity as it can be transferred between systems. The discussion highlights the distinction between energy conservation and the behavior of entropy in thermodynamic processes. Force is also not a conserved quantity in the same sense as energy. Understanding these concepts is essential for grasping thermodynamic principles.

Homework Statement

Which of the following quantities is conserved?
1) Energy
2) Heat

Hi logit167,

What do the laws of thermodynamics say about entropy?

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
