Problem 1.18 Calculate the rms speed of a nitrogen molecule at room temperature. Solution: Problem 1.18

Problem 1.17 Even at low density, real gases don’t quite obey the ideal gas law. A systematic way to account for deviations from ideal behavior is the virial expansion,,where the functions , , and so on are called the virial coefficients. When the density of the gas is fairly low, so that the volume per…

Problem 1.15 Estimate the average temperature of the air inside a hot-air balloon (see Figure 1.1). Assume that the total mass of the unfilled balloon and payload is 500 kg. What is the mass of the air inside the balloon? Solution: Problem 1.15

Problem 1.14 Calculate the mass of a mole of dry air, which is a mixture of (78% by volume), (21%), and argon (1%). Solution: Problem 1.14

Problem 1.13 A mole is approximately the number of protons in a gram of protons. The mass of a neutron is about the same as the mass of a proton, while the mass of an electron is usually negligible in comparison, so if you know the total number of protons and neutrons in a molecule…

Problem 1.12 Calculate the average volume per molecule for an ideal gas at room temperature and atmospheric pressure. Then take the cube root to get an estimate of the average distance between molecules. How does this distance compare to the size of a small molecule like or ? Solution: Problem 1.12

Problem 1.11 Rooms A and B are the same size, and are connected by an open door. Room A, however, is warmer (perhaps because its windows face the sun). Which room contains the greater mass of air? Explain carefully. Solution: Problem 1.11

Problem 1.10 Estimate the number of air molecules in an average-sized room. Solution: Problem 1.10

Problem 1.9 What is the volume of one mole of air, at room temperature and 1 atm pressure? Solution: Problem 1.9 Find more Schroeder solutions here.
