Kinetic Theory of Gases · Gas laws and molecular picture

One gas of n1n_1 mole of molecules at temperature T1T_1, volume V1V_1, and pressure P1P_1, and another gas of n2n_2 mole of molecules at temperature T2T_2, volume V2V_2, and pressure P2P_2, are mixed resulting in pressure PP and volume VV of the mixture. The temperature of the mixture is .
  1. (1)(T1+T2)/2(T_1 + T_2)/2
  2. (2)T1T2PV/(T2P1V1+T1P2V2)T_1T_2PV/(T_2P_1V_1 + T_1P_2V_2)
  3. (3)(T2P1V1+T1P2V2)/(T1T2PV)(T_2P_1V_1 + T_1P_2V_2)/(T_1T_2PV)
  4. (4)∣T1−T2∣/2|T_1 - T_2|/2
We corrected a printing error in the original paper

Source printed option (3) as “(T2P1V1+T1P2V2) (T1T2PV)(T_2P_1V_1 + T_1P_2V_2)\,(T_1T_2PV)” (the “/” missing).
