A gas of nitrogen molecules is at a temperature of 1000K. In this case molecule has 3 translational, 2 rotational, and 2 vibrational degrees of freedom per molecule, i.e. a total of 7.

1.1. [1pt] What is the root mean square velocity of the gas molecules in [m/s]?

ANSWER

1.2. [1pt] What is the total mean thermal energy per molecule in [J]?

ANSWER

1.3. [2pt] What is the heat capacitance of the gas per molecule, when the gas is heated under constant volume and under constant pressure (two different processes) in [k_B]?

Consider a classroom filled with air. Let’s approximate air as an ideal gas of N2-molecules (nitrogen) at normal conditions (P = 1 Bar and T = 300 Kelvin). Suppose the room has dimensions of 10 m by 10 m by 10 m (a pretty large auditorium). Let us also assume that N2 molecule has 5 degrees of freedom (3 translational and 2 rotational). In this problem you will need to provide numeric answers up to the first significant digit. 2.1...

Neon gas (a monatomic gas) and hydrogen gas (a diatomic gas) are both held at constant volume in separate containers. Each container contains the same number of moles n of each gas. You find that it takes an input of 300 J of heat to increase the temperature of the hydrogen by 2.50°C. Part A How many modes does a single hydrogen gas molecule have? (Assume the vibrational modes are "frozen out"). 3, all rotational kinetic 6, 3 translational kinetic...
