Personalized lecules have twice the mass of hydrogen gas molecules (H2).A container of helium-4 gas and a container of hydrogen gas are at the same temperature. What is the ratio of the average speed of the helium molecules to the average speed of the hydrogen molecules? Enter your response Why? Comes from 13.4 Kinetic Theory: Atomic and Molecular Explanation of Pressure and Temperature
At what temperature is the root-mean-square speed of nitrogen molecules equal to the root-mean-square speed of hydrogen molecules at 46 oC? (Hint: The molar mass of hydrogen atoms is 1.008 g/mol and of nitrogen atoms is 14.007 g/mol. The molar mass of H2 is twice the molar mass of hydrogen atoms, and similarly for N2.) The answer is in degree C.
Determine the following speeds (in m/s) for molecules of the diatomic gas hydrogen at a temperature of 815 K. Use 2.02 x 10-3 kg/mole as the molar mass for hydrogen molecules. (a) root mean square speed 3176 m/s (b) average speed Check your text for an expression which will allow you to determine the average speed of the gas molecules. Enter the temperature in degrees kelvin, take into consideration that we are dealing with a diatomic gas, and be sure...
1.Effusion is a process in which a gas escapes from a container through a small opening into a vacuum. In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 × 10-6 mol/h and an unknown gas effuses at a rate of 4.0×10-6 mol/h. Identify the unknown gas. 2.Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is...
