Homework Help Overview

The discussion revolves around the relationship between temperature, pressure, and the density of nitrogen gas, specifically examining how changes in these variables affect gas density. The original poster presents a scenario with given initial conditions and seeks to determine the density under new conditions.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the application of the ideal gas law and the relationship between density, temperature, and pressure. There are inquiries about the final result and confirmations of the calculations presented.

Discussion Status

The discussion appears to be progressing with participants confirming the calculations and results provided. However, there is no explicit consensus on the methodology used to arrive at the final density value.

Contextual Notes

Participants are operating under the assumption of ideal gas behavior and are discussing the implications of changing temperature and pressure on gas density without addressing potential deviations from ideal behavior.

Homework Statement


In temperature 273 kelvin and pressure 1.013*10^5 Pa, the density of nitrogen is 1,25 kg/m3. Find the density of this gas in temperature 330 kelvin and pressure 1.40*10^5 Pa.

T1=273 K; p1=1.013*10^5Pa; d1=1.25 kg/m3

T2=330 K; p2 =1.4*10^5 Pa. d2=?

Homework Equations


p1V1/T1=p2V2/T2
