Questions & Step-by-Step Solutions
What is the effect of increasing the number of gas molecules on the RMS speed?
Step 1: Understand what RMS speed is. RMS speed stands for Root Mean Square speed, which is a way to measure the average speed of gas molecules.
Step 2: Know that RMS speed depends on two main factors: temperature and molar mass of the gas.
Step 3: Recognize that the number of gas molecules does not affect the RMS speed. It only changes the total amount of gas present, not how fast the molecules are moving on average.
Step 4: Conclude that even if you increase the number of gas molecules, the RMS speed will stay the same as long as the temperature and molar mass remain constant.
