Two membranes filled with salt water are placed into separate tanks that are filled with water that has NO dissolved salt. Container 1 is rectangular (h=4, l=2, w=2), SA=2(lw+wh+lh), V=lwh. Container 2 is a cylinder (h=4, r=1), SA=2πrh+2πr², V=πr²h. So From which of these containers will the salt diffuse faster?
Calculate SA of Container 1 and Container 2.
Container 1 is 40, Container 2 is ≈ 31.
Therefore since the SA of Container 1 is greater, salt will diffuse from it faster.
