Задача 20132.

1 kmol gas being at a temperature T = 300 K 1 cools isochorically, whereupon its pressure is reduced by half. The gas then expands isobarically so that in the final state, its temperature is equal to the original. Show process diagram P, V. Find the entropy increment, increment of internal energy, do the work of A.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
