Homework Answers
35. According to charle's law,
V1/T1 = V2/T2
T1 = 20 + 273.15 = 293.15°K
T2 = 5 + 273.15 = 278.15°K
Therefore, V1 = 1.05393*V2
According to Boyle's law,
P1*V1 = P2*V2
Therefore, 1.5*(1.05393*V2) = P2*V2
Cancelling out common terms,
P2 = 1.58 atm . . . . . . . . Ans. (Option E)
36. Option B. Structure is given below:
