热一热二(国外英文资料) Physical chemistry examination paper (first, second law of thermodynamics) First, the multiple-choice questions (20 questions, 40 points) 1.2 points (0263) 1 mol monatomic molecular ideal gas, from the initial p1=, 202650, Pa, T1=, 273, K, along the path of the p/V= constant, reversibly changes to the final state of p2=405, and 300 Pa is H (A) 17.02, kJ (B), -10.21, kJ (C), -17.02, kJ (D) 10.21, kJ 3.2 points (0422) Known: Zn (s) + (1/2), O2ZnO, Delta, cHm=351.5, kJ, mol-1 Hg (L) + (1/2), O2HgO, Delta, cHm=, 90.8, kJ, mol-1 Therefore, the delta rHm of Zn+HgOZnO+Hg is: () (A) 442.2, kJ, mol-1 (B) 260.7, kJ, mol-1 (C), -62.3, kJ, mol-1 (D), -442.2, kJ, mol-1, 4.2 points (0030) What is the dimension of pressure, that is, the physical quantity in physical chemistry, usually called pressure? (A) momentum (B), force (C), kinetic energy (D) acceleration Area, time, area, time, area, time and quality 5.2 points (0477) How much volume of air does it take to complete 8 DM3 acetylene? (A) 20, DM3 (B) 120, DM3 (C) 100, DM3 (D) 4, DM3 6.2 points (0194) A gas at constant pressure and constant temperature heating process (no volume work) the heat absorbed by the same test temperature dTp constant pressure and constant volume process system increased with increasing temperature of the size of the dTV system. () (A) dTp, dTV (B), dTp = dTV (C), dTp, dTV (D), dTpdTV 7.2 points (0156) Which of the following is true? Because Delta Hp = Qp, so..: (A) the enthalpy is no longer a function of state (B) in constant pressure, and the exchange of system and environment during constant pressure (C) in a constant pressure process, enthalpy change does not measure the work done by the system (D) the delta U is not necessarily zero during constant pressure 8.2 points (0013) As shown in the case of an insulated vessel, a resistance wire is impregnated with the electric current for a period of time, such as a resistance wire, and the symbols of the Q, W, and system Delta U values of th
