Homework Answers
We know that molecular speed is directly proportional to square root of temperature and inversely proportional to square root of mass. So if a molecule has higher mass then it will has low molecular speed. From the plot it is seen that species 1 has lowest molecular speed so it most has largest mass.
So the correct answer is species 1
Add Answer to:
species 1,2,3,4
