An ideal gas is compressed at constant temprature what will be effect on internal energy |
| Answer» Wok done = nRTlnv²/v¹<br>du =0<br>Tp de ka ne paiu<br>As per first law of thermodynamics, conservation of energy is dq = du + pdV, where dq = thermal energy of gas du = change in internal energy of gas pdV = work done by gas in expanding due to change in volume dV If T = const., dT = 0 and d(pV) = 0 as pressure and If T = const., dT = 0 and d(pV) = 0 as pressure and volume are inversely proportional. Also, dq = pdV, which shows that there is no change in internal energy.Read more on Sarthaks.com - https://www.sarthaks.com/217713/an-ideal-gas-compressed-constant-temperature-will-its-internal-energy-increase-decrease | |
