Question 10, part g.Question 10: Coffee-cup calorimetry and heat capacityA 42.5 g metal sample at 96.0 degrees C is placed into 85.0 g of water at 21.6 degrees C in a coffee-cup calorimeter. The final temperature is 26.8 degrees C. Use Cs,water = 4.184 J g^-1 K^-1 and a calorimeter heat capacity of 18.0 J K^-1.Part g. If the calorimeter heat capacity had been ignored, would the calculated metal specific heat be too high or too low? Explain.

Question 9, part i.Question 9: Real gases, work, heat, and interpretationA 1.50 mol sample of CO2(g) is held at 35.0 degrees C in a 30.0 L container. For CO2, use a = 3.59 atm L^2 mol^-2 and b = 0.0427 L mol^-1. Use R = 0.082057 L atm mol^-1 K^-1 or R = 8.314 J mol^-1 K^-1 as appropriate, and 1 atm = 101325 Pa.Part i. If the gas expands reversibly and isothermally from 30.0 L to 45.0 L, calculate w for the ideal gas.
