Hydrogen pressure was at P1 in volume V1 and volume changes to V2 become equal to the pressure P2. The transition from the first state to the second occurred in two stages: first in isochore, followed by adiabatic. The amount of heat absorbed by the gas is equal to the Q, the increment of internal energy, work gas A. Determine the amount of heat absorbed by the Q, if P1 = 1750 kPa; V1 = 0,33 m ^ 3; P2 = 250 kPa; V2 = 0,68 m ^ 3.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
