In a thermodynamic process on an ideal monatomic gas, the infinitesimal heat absorbed by the gas is given by T Delta X,where T is temperature of the system andDelta Tis the infinitesimal change in a thermodynamic quantity X of the system. For a mole of monatomic ideal gas x = 3/2 "R h" (T/T_A)"+Rh)(V/V_A).Here, R is gas constant, V is volume of gas, T_Aand T_A are constants. The List-I below gives some quantities involved in a process and List-II gives some possible values of these quantities. If the process on one mole of monatomic ideal gas is as shown in the TV-diagram with P_0 V_0 = 1/3 RT_0,the correct match is, |
