Diffusion Quizzes & Trivia

Diffuse the word. I mean... spread the word. Science geniuses needed to take on our diffusion quiz! Unlike me, do you enjoy chemistry or physics? Let me give your brain a stir. Are you aware that substances like atoms and molecules move from areas of high concentration to areas of low concentration? Yes! That’s what diffusion is all about.

Do you know diffusion is also studied in other fields like biology and sociology? It is even studied in finance and economics too!For now, let’s stick to the sciences and see if your knowledge is concentrated or diffused. Put on your lab coat and fire up the Bunsen burner. We’re going to do some mind-blowing experiments. Let’s see how you do with the quiz on diffusion.

Diffusion Questions & Answers


Which of these molecules can not pass through a membrane to enter a cell?
1. StarchAs we observed in the Diffusion Through a Membrane lab, starch cannot pass through a semi-permeable membrane. We know this because the solution surrounding the cell we constructed remained amber, instead of turning purple. Starch is too larg
When is equilibrium reached after sugar is mixed with water?
The equilibrium is reached is number 3. The dissolved sugar molecules are evenly distributed throughout the solution. Some may think that the salt solution and sugar solution is the same but there are some differences between the two. For example, i
What is simple diffusion defined as?
Both of this guys the wrong idea the real answer is 3 because it goes across the membrane and that is why the dye molecule is know going through the bottle. I'm sorry that this people didnt know the answer
What would a solution with 1.5% saline in it be considered as?
(c) Hypertonic A saline solution with 1.5% saline would be considered hypertonic when going in the body. The blood in our bodies has a saline concentration of 0.9% on average. A hypertonic solution, for those who don’t know, is a solution that
