Finding Pressure when given change in temperature

Click For Summary
SUMMARY

The discussion focuses on calculating the new pressure of methane gas in a 1.8L flask when heated from 28°C to 164°C, using the ideal gas law. The user correctly identifies the relationship P1/T1 = P2/T2 to find the new pressure, resulting in a calculated pressure of approximately 1.6485 atm. The initial conditions were 863 mmHg and 28°C, and the calculations were performed using absolute temperature in Kelvin. The user acknowledges the need for significant figures but confirms the method is sound.

PREREQUISITES
  • Understanding of the Ideal Gas Law
  • Knowledge of temperature conversion to Kelvin
  • Familiarity with pressure units (atm and mmHg)
  • Basic algebra for manipulating equations
NEXT STEPS
  • Study the Ideal Gas Law and its applications in various scenarios
  • Learn about temperature conversions and their importance in gas calculations
  • Explore significant figures and their role in scientific calculations
  • Investigate other gas laws such as Boyle's Law and Charles's Law
USEFUL FOR

Chemistry students, physics enthusiasts, and professionals working with gas laws and thermodynamics will benefit from this discussion.

I have this problem: A 1.8L flask is filled with methane,CH4, at 863mmHg and 28C. if the flask is then heated to 164C what is the new pressure in atm?(assume ideal gas behaviour)

I know i need to use on of the gas laws but none of them seem to fit the picture.
thanks

Ive done some working
am i right in using P1V1/N1T1=P2V2/N2T2?

therefore P1/T1 = P2/T2
(using atm and K) 1.135526313/301 = P2/437
P2 = 1.6485 atm
 
Way too many significant digits, but otherwise OK.
