Q: The average speed of gas molecules is given by which of the following formulas? (2023)
Solution: The average speed of gas molecules is given by the formula v_avg = sqrt(8kT/πm), where k is the Boltzmann constant, T is the temperature, and m is the mass of a molecule.
Steps: 5
Step 1: Understand that we are looking for the average speed of gas molecules.
Step 2: Identify the formula that represents the average speed of gas molecules.
Step 3: The formula is v_avg = sqrt(8kT/πm).
Step 4: Recognize the variables in the formula: k is the Boltzmann constant, T is the temperature, and m is the mass of a molecule.
Step 5: Remember that this formula helps us calculate how fast gas molecules are moving on average.
