Question

Two moles of an ideal gas is expanded isother-
mally and reversibly from 1 litre to 10 litre at
300 K. The internal energy change (in KJ)
for the process (R = 8.3J)
1) 11.4 KJ
2) -11.4 KJ
3) O KJ
4) – 4.8 KJ​

Answer 1

Answer:

Zero

Explanation:

When gas is expand isothermally , temp remains same , internal enrgy remains same.

first law of thermodynamics.

del Q = del U + W.

when gas gonna expaind isothermally , internal enrgy change gonna be zero.
