Finding new Pressure in cylinder when compressed

Click For Summary
SUMMARY

The discussion centers on calculating the new pressure in a cylinder when a piston compresses the gas. The relationship between pressure (P) and volume (V) is defined by Boyle's Law, which states that at constant temperature, the product of pressure and volume remains constant (PV = constant). Participants emphasize the importance of understanding this inverse relationship to determine the new pressure after compression.

PREREQUISITES
  • Understanding of Boyle's Law in thermodynamics
  • Basic knowledge of gas laws and properties
  • Familiarity with pressure and volume measurements
  • Concept of constant temperature in gas behavior
NEXT STEPS
  • Study the derivation and applications of Boyle's Law
  • Explore real-world examples of gas compression in engines
  • Learn about the Ideal Gas Law and its implications
  • Investigate the effects of temperature changes on gas pressure
USEFUL FOR

Students in physics or engineering, mechanical engineers, and anyone involved in thermodynamics or gas behavior analysis will benefit from this discussion.

I know how to setup the entire problem i just don't know how to calculate the new pressure after the piston is compressed.

At constant temperature P is proportional to 1/V , or PV=constant.
