AI Thread Summary
To solve the Charles' Law problem regarding the volume change of a gas at constant pressure when the temperature changes from 38 to 132°C, the correct approach involves converting the temperatures to Kelvin. The initial equation used was V1*132 = V2*38, leading to the ratio V2/V1 = 132/38. However, the temperatures must be converted to Kelvin for accurate calculations, which resolves the issue. The correct factor for volume change is derived from the Kelvin values, ensuring the application of Charles' Law is accurate. Understanding the importance of temperature conversion is crucial in gas law problems.

Homework Statement


A gas is kept at constant pressure. If its temperature is changed from 38 to 132°C, by what factor does the volume change?

Homework Equations


V1T2=V2T1

The Attempt at a Solution


V1*132=V2*38
V2/V1=132/38
V2/V1=66/19

Am I just reading something wrong or did just use the wrong law or something?

solved my problem. I needed to first convert the temp to kelvin then invert that number to get my factor.
 

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...
