Using the approximation for small , estimate the fraction of nitrogen molecules at a temperature of K that have speeds between 290 m/s and 291 m/s. A nitrogen molecule has a mass of kg.
Find the ratio for hydrogen gas at a temperature of 77.0 K. Use a molar mass of 2.02 g/mol for hydrogen gas.
An incandescent light bulb is filled with neon gas. The gas that is in close proximity to the element of the bulb is at a temperature of K. Determine the root-mean-square speed of neon atoms in close proximity to the element. Use a value of 20.2 g/mol for the molar mass of neon.
