Questions & Step-by-Step Solutions
What is the root mean square speed of gas molecules directly proportional to?
Step 1: Understand that the root mean square speed (v_rms) is a measure of the average speed of gas molecules.
Step 2: Know that temperature is a measure of how hot or cold something is, and in this case, we are using absolute temperature (T).
Step 3: Recognize that the equation v_rms = sqrt(3kT/m) shows the relationship between v_rms, temperature (T), and other constants (k and m).
Step 4: Identify that in the equation, the square root of the absolute temperature (sqrt(T)) is part of the formula for v_rms.
Step 5: Conclude that since v_rms is proportional to sqrt(T), it means that as the absolute temperature increases, the root mean square speed of gas molecules also increases.
