Gases are sold and shipped in metal tanks under high pressure. A tank of compressed air has a volume of 25.9 L and is pressurized from 1 atm to 17.4 atm at T = 298 K. What work (in kJ) had to be done in filling this tank if the compressor operates at 17.4 atm? (Hint: What volume did the air occupy before it was compressed?) i kJ

Let's use our knowledge of constant volume (bomb) calorimetry to determine the heat energy in a given food sample, say a hamburger. A typical hamburger has a serving size of 105 g and consists of approximately 20% protein (21.0 g), 33% fat (34.7 g), and 47% carbohydrate (49.3 g). Assume that the heat capacity of the bomb calorimeter is 8.39 kJ K-¹, and the increase in water temperature was 13.2 K. Q5.38 Homework Unanswered How many Calories (Cal) are in the hamburger described above?

The enthalpy of reaction for the formation of 2.00-mol ozone from 3.00-mol O2 (g): 3 O2 (g) à 2 O3 (g) is ∆Horxn = 429 kJ at 1 atm and 25 oC. In this question, O2 (g) and O3(g) are rigid molecules and have the ideal gas behavior. Their molar heat capacities at constant pressure are independent of temperature, and follow the values shown in our lecture note (Page 56 in Chapter 2 Part 1). At -35 oC, the enthalpy of reaction for the above reaction ( 3 O2 (g) à 2 O3 (g) ) should be _______ 429 kJ. Insufficient information equal to greater than less than
