The average kinetic energy of the molecules in a gas sample depends only on the temperature,...
The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed=√3RTM where R=8.314 J/(mol⋅K) and M is molar mass in kilograms per mole. Note that a joule is the same as a kilogram‑meter squared per second squared (kg·m2/s2). What is the rms speed of Cl2 molecules at 471...

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...

2. An aluminum scuba tank, which has an internal volume of 11.1 L, is filled with air to a pressure of 3000 psi when at room temperature (i.e. 20.0 OC). A diver takes the tank into seawater, where the water temperature is 46 degrees Fahrenheit (i.e. 8.00OC). To what pressure does the air in the tank drop? (The thermal coefficient of expansion for aluminum is 24.0x10-6 OC -1 .) Answer: 2880 psi Don't need #2, just #3 please. 3. For...
