What Celsius Value of Absolute Zero Does the Calibration Yield?

AI Thread Summary
The discussion revolves around calibrating a constant-volume gas thermometer using dry ice and boiling ethyl alcohol, yielding pressures of 0.861 atm and 1.569 atm, respectively. The main question is to determine the Celsius value of absolute zero based on the provided temperatures and pressures, with a calculated result of -273.47°C. Participants express some confusion regarding the question's intent, suggesting it aims to demonstrate the accuracy of constant-volume thermometers across a wide temperature range. Additional resources were shared to clarify the concept of absolute zero. The conversation highlights the importance of understanding the calibration process in thermometric measurements.

Homework Statement



A constant-volume gas thermometer is calibrated in dry ice (that is, carbon dioxide in the solid state, which has a temperature of -80.0°C) and in boiling ethyl alcohol (78.0°C). The two pressures are 0.861 atm and 1.569 atm.
(a) What Celsius value of absolute zero does the calibration yield? (Express your answer to the nearest 0.01°C.)
°C:eek:

Homework Equations



So I'm given this T= T1-p1X(T2-T1/P2-P1)= -273.47

The Attempt at a Solution



I understand the equation and it works with the values that are given however i don't get what exactly the question is looking for if someone can clear it up i would really appreciate it :shy:
 
Physics news on Phys.org
well, most other kinds of thermometers have a specific range, outside of which they would be inaccurate. i think the question just wants to show that const vol thermometers are accurate over a wide range.

anyhow, i did some googling and came up with this. http://www.ux1.eiu.edu/~cfadd/1360/19Temp/Absolute.html
 

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...
