Question

Make one PV diagram showing the following sequential processes: 2.00 moles of an ideal gas at 400K, 1.00 atm. 1. expand isothermally from 65.6 L to 131.3 L at 400 K. 2. cooled isobarically from 65.6 L, 200 K 3. heated isochorically from 200 K back to 400 K.

Answer 1

for Isothermal process. Temperature = Conectant ... from ideal Gas equation, PV = Constant PTL va 18 thermal enanbbion as Volieme increases in direction of arrow for rebosic 2 for Iphouc proces p- Constant P T wili - > Isobaric espansion for Isochoric process I = Constant

Ayo Kelvin latm in het B 0.Sabont - Zokic ill yo kelvin NTB 65.6 liters 131.3 liter V for Process A B Isothermal expansion for Process B C as pressure is Conetant so as we decreases the leolume Temperature will also decreases (for Constant pressure Volume x Temperature). for process C A TAS Voleme is Conetant so, Pressure & Temperature So as we increase the temperature Pressure will also increases. I for AB PV = Constant, PAVA = Pp Up Po PA VA (1) (65.6) B ! (31.3) for B C Isobaric process - = 0.5 abm. so, Pg=Pc
