N 6 moles of a monatomic ideal gas initially fills a v0

Reference no: EM13582952

n = 6 moles of a monatomic ideal gas initially fills a V0 = 0.35 m3 container at P0 = 85 kPa. The gas undergoes an isobaric expansion to V1 = 1.3 m3. Next it undergoes an isovolumetric cooling to its initial temperature T0. Finally it undergoes an isothermal compressions to its initial pressure and volume.

Randomized Variables

n = 7 moles V0 = 0.35 m3 P0 = 85 kPa

V1 = 1.3 m3

Part (a) Identify the P-V diagram that correctly represents this three step cycle. SchematicChoice :

W1 = __________________________________________

Part (c) Calculate the heat absorbed Q1, in kilojoules, during the isobaric expansion (first process). Numeric : A numeric value is expected and not an expression.

Q1 = __________________________________________

Part (d) Write an expression for the change in internal energy, ?U1 during the isobaric expansion (first process). Expression :

?U1 = __________________________________________
