When 2 litre of ideal gas expands isothermally into vacuum to a total volume of 66 litre, the change in internal energy is _____ J. (Nearest integer)

Correct answer

0

Step-by-step solution

For ideal gas U=f(T)andforisothermalprocess,U = f\left(T\right) and for isothermal process,\Delta U = 0,<br/>Also,<br />Also{P}_{ext} = 0$, thus work done in vacuum is also zero. Internal energy is a fuction of temperature.
