1.	A monoatomic gas is supplied heat Q very slowly keeping the pressure constant. The work done by the gas isA. `(2)/(5) Q`B. `(3)/(5) Q`C. `(Q)/(5)`D. `(2)/(3) Q`
Answer» Correct Answer - D For monoatomic gas , `(Delta U)/(Q) = 1/3 or Delta U = Q/3` From the first law of thermodynamics `Q = Delta U +W :. W = (2//3)Q`.
