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...
