(a) Estimate the specific heat capacity of sodium from the Law of Dulong and Petit. The molar mass of sodium is 23.0 g/mol. (b) What is the percent error of your estimate from the known value, 1230 J/kg ? `
Temperature-Dependent Heat Capacity At low temperatures, the specific heats of solids are typically proportional to T3. The first understanding of this behavior was due to the Dutch physicist Peter Debye, who in 1912, treated atomic oscillations with the quantum theory that Max Planck had recently used for radiation. For instance, a good approximation for the specific heat of salt, NaCl, is c =3.33× 104 J ⎛ ⎞ kg·k ⎝ T 321 K ΘD, and the formula works well when ⎠ T

1. A three-liter tank contains two gram-moles of nitrogen at − 150.8o C. Estimate the tank pressure using the ideal gas equation of state and then using the Virialequation of state truncated after the second term. Taking the second estimate to be correct, calculate the percentage error that results from the use of the ideal gas equation at the system conditions. Data for nitrogen: Tc = 126.2 K, pc = 33.5 atm, and ω = 0.04012. 2. One mole of propane gas is to be expanded from 0.001 m3 to 0.040 m3 while incontact with a heating bath at 100o C. The expansion is not reversible. The heatextract from the bath is 600 J. Determine the work for the expansion using theVan der Waals equation of state.

You have two identical containers, each filled with 1 mol of an ideal gas at identical temperature - one is filled with Ne, the other is filled with H2 . Assume atomic mass of Ne > atomic mass of H2a) You increase the temperature of both containers by the same value. Do you need the same / more / less energy to increase the temperature of the Ne compared to H2 ? Argue and explain.b) How does the average speed of gas atoms / gas molecules in both containers compare to each other? Do the gases have the same speed in both containers or does one gas move faster or slower than the other? Argue and explain.
