Problem 32

Calculate the change in entropy that occurs in the system when 1.00 mole of diethyl ether $\left(\mathrm{C}_{4} \mathrm{H}_{10} \mathrm{O}\right)$ condenses from a gas to a liquid at its normal boiling point $\left(34.6^{\circ} \mathrm{C}\right) .$ See Table 11.7 for heats of vaporization.

So for this problem you have see for H 10 0 going from a gas to liquid and you want to find out that tribute changes. And so if you look in your textbook, you can find the entropy of vaporization is equal to 26 point, uh, killed Jules promote and temperature. Is that 34.6 degrees C? So I found out that s we understood at the H over tea J equals 26.5. And I went ahead and converted just to Calvin. But you don't have to Just make sure you keep your head straight. 307.75 Kelvin, That equals zero point 08681 killer Jules promote Calvin.
