1.	Two identical vessels A & B contain equal amount of ideal monoatomic gas. The piston of A is fixed but that of B is free. Same amount of heat is absorbe3d by A & B 's internal energy increases by 100 J the change in internal energy of A is
Answer» `100 J ` `(500)/(3)J` `250 J` none of these Solution :`nC_PtriangleT = triangleQ for B` `triangleQ = TRIANGLEU for A`
