    Mass Pv=nrt
AI Thread Summary
The discussion revolves around calculating the mass of a piston and the height of an ideal gas column in a vertical cylindrical tank. The tank contains 1.75 moles of gas at a pressure of 1.00 atm and a temperature of 20.0°C, with a radius of 10.0 cm. The height of the gas column supporting the piston has been correctly calculated as 1.34 meters. However, there is confusion regarding how to determine the mass of the piston using the ideal gas law equation, pv=nrt, due to a lack of provided units. Clarification on unit conversion and application of the gas law is necessary for solving the mass of the piston.

Homework Statement



A vertical cylindrical tank contains 1.75 of an ideal gas under a pressure of 1.00 at 20.0. The round part of the tank has a radius of 10.0 , and the gas is supporting a piston that can move up and down in the cylinder without friction.
What is the mass of this piston?
How tall is the column of gas that is supporting the piston?

Homework Equations



pv=nrt

The Attempt at a Solution

for the 2nd question i got h=1.34m and that answer is correct. I have no clue how to find the mass of the piston using pv=nrt.

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 hanged 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...
