4. From the results of the first experiment, what can you say about the effect of molecular size
on the rate of diffusion?

Mass of the molecules diffusing: Heavier molecules move more slowly therefore they diffuse more slowly. The reverse is true for lighter molecules. Temperature Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.

I'm sorry to hear that. i will try to answer your other questions if it is within my ability. : )answers: my favourite colour is black.my favourite food is pasta.my favourite school subject is english, but i do also like lunch time.my least favourite subject is history as well as geography. i have currently garnered a quite equal hatred for both of the subjects.what about you? well, you for the points. : )
