Discussion Overview

The discussion revolves around an experiment aimed at verifying the gas constant R using a lighter. Participants explore how to determine the pressure inside the lighter and the applicability of the ideal gas law in this context.

Discussion Character

  • Homework-related
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant seeks assistance in measuring the pressure inside a lighter using the equation PV=nRT.
  • Another participant suggests using the combined gas law and inquires about the possibility of constructing a manometer for the experiment.
  • A different participant argues that measuring the pressure inside the lighter is unnecessary and points out that the gas is in a liquid form, which may not conform to the ideal gas law.
  • A later reply acknowledges the previous point but claims to have found a way to measure the pressure, indicating a potential solution.

Areas of Agreement / Disagreement

Participants express differing views on the necessity and feasibility of measuring the pressure inside the lighter, with some asserting it is unnecessary while others propose methods to do so. The discussion remains unresolved regarding the best approach to take.

Contextual Notes

There are limitations regarding the assumptions about the state of the gas inside the lighter and its adherence to the ideal gas law, which are not fully explored in the discussion.

Homework Statement


I need to do an experiment to verify the gas constant R and I can only use a lighter. The equation useful is PV=nRT but I don't know how I can find the pressure inside the lighter. Any help is appreciated! :D

Homework Equations



I don't know what other equation might be used other than PV=nRT

You may be able to use combined gas law to solve this. Does you experimental design allow for the construction of a manometer?
 
There is no need to measure the pressure inside the lighter. Besides, it won't help, as the gas inside is in a liquid form, so it doesn't obey the ideal gas law.

Yeah that's right, but I found a way to do it so it's all good now :)
