What is the final volume? 20046 PHY 115 Problem 12 26 Problem 12.26 Part B What is theinitial temperature? 00050 mol of gas follows the hypertoictrajectory shown in Express your answer using two significant figures.

Explanation / Answer

at point "i"

Pi = initial pressure = 3 atm = 3 x 1.01 x 105 Pa

Vi = initial volume = 100 cm3 = 100 x 10-6 m3

n = number of moles = 0.0050

Ti = temperature at "i"

using the equation

Pi Vi = n R Ti

(3 x 1.01 x 105) (100 x 10-6) = (0.0050) (8.314) Ti

Ti = 728.89 K

b)

since the process is isothermal

hence Tf = Ti = 728.89

c)

Pf = initial pressure = 1 atm = 1 x 1.01 x 105 Pa

Vf = initial volume

using the formula

Pf/Vf = Pi/Vi

(1 x 1.01 x 105)/Vf = (3 x 1.01 x 105) /(100 x 10-6 )

Vf = 0.000033 m3
