12. Calculate the increase in entropy when mixing VA m3 of gas A at temperature TA and VB m3 of gas B at temperature TB. The process is carried out at V = const. Assume that these substances obey the laws of ideal gases, the initial pressure is 1.013 * 105 Pa, the final pressure of the mixture is R.
