Questions & Step-by-Step Solutions
The average speed of gas molecules is given by which of the following expressions? (2022)
Step 1: Understand that we are looking for the average speed of gas molecules.
Step 2: Recognize that the average speed can be calculated using a specific formula.
Step 3: The formula for average speed is v_avg = √(8RT/πM).
Step 4: Identify the variables in the formula: R is the universal gas constant, T is the temperature in Kelvin, and M is the molar mass of the gas in kg/mol.
Step 5: Remember that this formula is derived from the kinetic theory of gases, which relates temperature and molecular motion.
