    Gases Pv=nrt
AI Thread Summary
The discussion centers on the ideal gas law equation PV=nRT and its implications for gas behavior in varying volumes. It highlights that gases do not have a fixed volume and will expand to fill their containers. When considering different volumes, at constant temperature and number of moles, either pressure or temperature must change according to the equation. This relationship is crucial for understanding how gases behave under different conditions. The equation serves as a fundamental tool for predicting gas behavior in various scenarios.

Homework Statement


I was studying about gases..and a thought struck me: we are taught that gases have no fixed volume. They occupy whole of volume of container in which they're placed.
so what are we trying to calculate by the equation PV=nRT . I mean at a particular P T and n,
place the gas in containers having different volumes.

you can't … if V is different, then one of the others must be different also (usually the pressure)

that's why the equation is important! :biggrin:​
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
