    Gas Moles Solid
AI Thread Summary
The discussion revolves around a homework problem involving 2.0 moles of a monatomic gas and 2.0 moles of an elemental solid, where the gas pressure decreases by 50 degrees Celsius at constant volume. Participants express confusion over the problem's wording, particularly regarding the pressure change being stated in temperature units, which is unconventional. There is speculation that the problem might have intended to indicate a 50% decrease in pressure rather than a temperature change. Clarification on the relationship between pressure and temperature in this context is sought, as it is crucial for solving the problem. Understanding the thermodynamic principles involved is essential for determining the temperature change in the solid.

2.0 moles of a monatomic gas interacts thermally with 2.0 moles of an elemental solid. The gas pressure decreases by 50 degrees C at constant volume. What is the temperature change in the solid?


I missed this day in class and I have no idea where to even begin...

The question doesn't seem to make sense, as pressure is not measured in units of temperature, unless I am missing something?
 


It probably says or intends 50%, not 50oC.
 
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 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
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...
