1.	An ideal gas undergoing a change of state from A to B through four different paths I, II,III and IV as shown in the P-V diagram that lead to the same change of state tyhen the change in internal energy is
Answer» same in I and II but not in III and IV same in III and IV but not II and II same in I, II and III but not IIV same in all the four cases Solution :From the givne INITIAL stte A to final STATE B, change in internal energy is same all the four cases as it is independent of the PATH from A to B .
