(Experiment 1: Diffusion through a liquid) Does the rate of diffusion correcspond with the molecular weight of the dye?

1 answer:

3 0

The answer to this question would be: False

The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.

The right option is; b. the water caused an increase in temperature of the air inside the ball and an increase in pressure.

The dent (hollow area formed by pressing or hitting) from the ping-pong ball disappeared because energy was transferred from the hot boiling water in which the ball was placed to the air inside the ball. This transferred energy will increase the temperature of the air inside the ball and the air molecules will begin to move faster with a greater force. Hence, causing an increase in pressure.
