`Delta U=0` for

For a cyclic process,the condition is (A) Delta U=0 only (B) Delta H=0 only (C) Delta U>0 and Delta H>0 (D) both Delta U=0 and Delta H=0

Establish a realtion between Delta H and Delta U for a gaseous reaction:

The process in which the value of Delta U=0 is :

For an isolated system, Delta U=0 . What will be DeltaS ?

A sample of liquid in a thermally insulated container is stirred to increase the temperature.For this process " (A) "w 0;q>0;Delta U>0] , " (c) "w 0;Delta U,=0 , " (D) "w>0;q=0;Delta U>0

For an isolated system Delta U = 0 , what will be Delta S ?

Which is always false for isothermal process "(A) "W!=0 , "(B) "Delta U!=0 , " (C) "Delta T=0 , " (D) "q=0

Correct relation for isothermal reversible expansion of an ideal gas is Delta U=0 , Delta S=0 , Delta G=-T Delta S , Delta H=0
