Find the growth of temperature of the gas

Click For Summary
SUMMARY

The discussion centers on calculating the temperature growth of a gas under constant pressure conditions. A mass of 3 moles of gas is heated from an initial volume of 40 liters to a final volume of 60 liters at a pressure of 1.5 atm. Utilizing the ideal gas law, represented by the equation pV=nRT, participants confirm that the final temperature is 121 K. The relationship between volume and temperature is established through the equation V1/V2=T1/T2, which is crucial for solving the problem.

PREREQUISITES
  • Understanding of the ideal gas law (pV=nRT)
  • Knowledge of gas laws, specifically Charles's Law
  • Familiarity with the concepts of moles and pressure in thermodynamics
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the derivation and applications of the ideal gas law (pV=nRT)
  • Learn about Charles's Law and its implications for gas behavior
  • Explore real-world applications of gas laws in engineering and physics
  • Investigate the effects of pressure changes on gas temperature and volume
USEFUL FOR

This discussion is beneficial for students studying thermodynamics, physics enthusiasts, and anyone involved in chemistry or engineering who needs to understand gas behavior under varying conditions.

Homework Statement


A mass of 3 mole gas is heated in a constant pressure of 1.5 atm, expanding from 40 litre to 60 litre. Find the temperature growth.

Homework Equations


V1/V2=T1/T2.

The Attempt at a Solution


I thought to write V1/V2=T1/T2. But I don't know T1. The answer is 121 K in my book.

Don't you know the ideal gas equation? Can you write it down? From this, given P, V, and N, you should be able to calculate T.
