A monatomic ideal gas initially fills a container of volume V = 0.25 m^3 at an initial pressure of P = 270 kPa and temperature T = 325 K. The gas undergoes an isobaric expansion to V_2 = 0.55 m^3 and then an isovolumetric heating to P_2 = 520 kPa. Calculate the number of moles, n. contained in this ideal gas. Calculate the temperature of the gas. in kelvins, after it undergoes the isobaric expansion. Calculate the change in entropy of the gas. in kilojoules per kelvin. as the material undergoes the isobaric expansion. Calculate the change in entropy of the gas. in kilojoules per kelvin, as the material undergoes the isochoric process.

Explanation / Answer

a) PV = nRT

(270*10^3)/(1.0125*10^5) *0.25 = n*0.0821*325

n = 0.025

number of moles = 0.025

b) V1/T1 = V2/T2

0.25/325 = 0.55/T2

T2 = 715 K

c) dS = nRln(v2/v1)

dS = 0.025*0.0821 ln (0.55/0.25)

dS = 0.0016 J/K
