Thermodynamics: P-V diagram question

Click For Summary
SUMMARY

The discussion focuses on a monoatomic ideal gas undergoing a linear process defined by the equation P/P0 + V/V0 = 1. The objective is to determine the volume at which the process transitions from exothermic to endothermic. Key parameters include P0, the pressure at nearly zero volume, and V0, the volume at negligible pressure. The relevant thermodynamic equation dU + w = dQ is highlighted, emphasizing that internal energy (U) is a function of temperature.

PREREQUISITES
  • Understanding of monoatomic ideal gas behavior
  • Familiarity with P-V diagrams and their interpretation
  • Knowledge of thermodynamic equations, particularly dU + w = dQ
  • Concept of exothermic and endothermic processes
NEXT STEPS
  • Study the derivation and application of the ideal gas law
  • Learn how to construct and analyze P-V diagrams for various thermodynamic processes
  • Explore the implications of internal energy changes in thermodynamic systems
  • Investigate the criteria for identifying exothermic versus endothermic reactions
USEFUL FOR

Students studying thermodynamics, physics enthusiasts, and educators looking to deepen their understanding of gas behavior and thermodynamic processes.

Homework Statement


A monoatomic ideal gas undergoes a linear process whose equation is given by P/po+V/vo=1. find the volume when the process turns from an exothermic to an endothermic one. P-Pressure V-volume
Po= pressure when volume is nearly 0 and Vo is the volume when pressure is negligible.
i couldn't upload the P-V diagram hence I've given the suitable equation for the curve(straight line with intercept Po and Vo) and the relevant parameters.

Homework Equations


dU+ w=dQ.
U is a function of temperature only
w is the pressure-volume work of the gas [/B]

The Attempt at a Solution


i tried to maximize the temperature function but nothing was working :cry:

Our rules do not allow the helpers to help unless you show your attempt. What you said is not enough.

Why? What does that have to do with the process being endothermic or exothermic?
