    Isochoric Process
AI Thread Summary
The discussion focuses on calculating the temperature in a sealed tank during an isochoric process, where the volume remains constant. Initially, the tank contains air at 3.00 atm and 20.0°C. When cooled to a pressure of 1.00 atm, the temperature calculation was attempted using the formula P/T=const. The error identified was the need to express temperature in Kelvin rather than Celsius for accurate calculations. The correct approach emphasizes the importance of unit conversion in thermodynamic equations.

A 3.00-L tank contains air at 3.00 atm and 20.0 C. The tank is sealed and cooled until the pressure is 1.00 .
What is the temperature then in degrees Celsius? Assume that the volume of the tank is constant.



P/T=const

3/20=1/T, T=6.67 C

Why it's not right?

nvm, i got it
 
temp should be expressed in kelvin units not "C"
 
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...
