One mole of an ideal gas at 300 K is expanded isothermally from an initial volume of 1 litre to 10 litreThe AE for this process is(A) 163.7 cal(R 2 cal mot1 K-1) -(C) 138.1 cal(B) zero(D) 9 lit atm |

Answer» As given process expanded isothermally means at constant temperature ΔT = constant We known that the internal energy of gases depend on the temperature as we increases the temperature the kinetic energy of molecules increases that increases the internal energy of molecules. Therefore, the internal energy of gases also remained constant at constant temperature So for given isothermal process ΔE = 0 |
