Question : 40/60 One mole of an ideal monoatomic gas is kept in a volume V and is at temperature T. If the volume and temperature of the gas are respectively changed to V1 and T1 in such a way that the entropy of the gas is unchanged, then which of the following is incorrect (A) V=2V, T = T/2 (C) V 4V, T = 8T (B) V= 8v, T' = T/4 (D) V= V/2, T' = 2T
