1a. A sample of argon gas at a pressure of 909 mm Hg and a temperature of 23 °C, occupies a volume of 11.2 liters. If the gas is heated at constant pressure to a temperature of 58 °C, the volume of the gas sample will be_______L?

1b. A sample of methane gas at a pressure of 0.535 atm and a temperature of 231 °C, occupies a volume of 479 mL. If the gas is heated at constant pressure until its volume is 591 mL, the temperature of the gas sample will be_______°C?

Expert Solution

1a.

pressure is constant

initial final

V1 = 11.2L V2 =

T1 = 23+273 = 296K T2 = 58+273 = 331K

V1/T1 = V2/T2

V2 = V1T2/T1

= 11.2*331/296 = 12.52L >>>>>answer

1b.presure is constant

initial final

V1 = 479ml V2 = 591ml

T1 = 231+273 = 504K T2 =

V1/T1 = V2/T2

T2 = V2T1/V1

= 591*504/479 = 621.84K

621.84-273 =348.84⁰C >>>answer

Argon gas is initially at a pressure of 10 bar and temperature of 45oC (state 1), while occupying a volume of 0.8 m3 in a frictionless piston-cylinder arrangement. The gas then undergoes a reversible constant volume process to a pressure of 6 bar (state 2), followed by a constant pressure process in which the temperature is restored to 45oC (state 3). a) Sketch the processes on T-s and p-v diagrams b) Assuming perfect gas behaviour determine i) The work done...
