Given A ≡ U – TS, derive the corresponding Maxwell relation.

5.- Nitrogen gas occupies a volume of 4.30 L at 54°C. If its volume increased to 7.80 L at the same pressure. Calculate the final temperature in kelvin. 235k 2k 593.163k 334.43k 200k

7. When detern ing the mass of a liquid, ras in a hurry and did not allow enough time for the temperature of the flask to reach the temperature of the boiling water bath. The student recorded the temperature of the gas as 100.0°C when it was only 80.0°C, Is the molar mass calculated by the student higher or lower than the accepted molar mass, or does this error have no effect on the calculated result? Briefly explain your answer # 2/HB Office DEPOTS b) If the student assumed the volume of the flask was 125 mL (as marked by the side of the flask) rather than measuring the volume experimentally, would the unknown's calculated molar mass be too high, too low, or unaffected? Explain. # 2/HB 4
