SUMMARY

The discussion centers on calculating the heat absorbed by a gas in a cylinder with a piston, in contact with a heat reservoir at 353 K. The gas is maintained at a constant pressure of 1.01 x 105 N/m2 while expanding by 1.5 x 10-5 m3. The work done by the gas is calculated using the formula W = P x ΔV, leading to a result of 1.15 J. The temperature of the reservoir is relevant for determining the number of moles of gas, although the primary calculation focuses on work done at constant pressure.

PREREQUISITES
  • Understanding of the Ideal Gas Law
  • Familiarity with thermodynamic principles, specifically work and heat transfer
  • Knowledge of pressure-volume work calculations
  • Basic concepts of moles and gas behavior at constant temperature
NEXT STEPS

  • Explore the concept of isothermal expansion and its implications
  • Investigate how to calculate the number of moles of gas using temperature and pressure
USEFUL FOR

Students studying thermodynamics, physics enthusiasts, and professionals in engineering fields focusing on heat transfer and gas behavior.

A cylinde with a piston in contact with a heat reservoir at 353 k. While keeping this gas at constant temp and pressure of 1.01 x 10E5 n/m2 we permit he gas to expand by 1.5E-5 m3. How much heat does the gas absorb?

Is it just p x v = w and w = q to get an answer of 1.15 j? Cause i feel like the temp of the reservoir needs to be used somehow...

the pressure and temperature is constant. So, the change in volume only depends on the work done by the gas and the constant pressure.

Work=integral of pressure times dV

So, yea, since the gas absorbs some heat, the particles will expand to a new volume and a dV of 1.5E-5m^3

If your calculations are correct, then you are fine.

The temperature would be used to calculate the amount of moles of the gas and other factors. They are letting you off easy on this. What physics are you in?
