In this video, we look at diffusion. I take you through the concept of diffusion and then we look at three factors that affect the rate of diffusion.
This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.

@ELLIPTICALWR 2 года назад

if AQA are telling us the major focus of the exams doesnt that mean the country will perform higher and therefore grade boundaries would be higher so isnt it pointless?

@RSS1350 2 года назад

Exactly

@ellaashford6069 2 года назад

i think the point is that revising alll the specification is quite stressful so its cutting down the things we need to know and showing us which bits we need to focus on to get high marks but yeah it is pointless in a way

@ilna4813 2 года назад

No, that isn't how it works. Exam markschemes and grade boundaries are created after exams, because they have to look at how students performed and say if everybody answered the questions well, they might decide to make grade boundaries higher to prevent grade inflation.

When the diffusion gradient is lower why does it cause it to be slower

@kyllakshanahilan4044 3 года назад

So what about the act of particles moving from an area of lower concentration to higher concentration?

@Freesciencelessons 3 года назад

That's active transport. There's a video on that.

sir what is the first factor affecting diffusion?

@charliebrett7510 5 лет назад

The first factor he mentioned was the concentration gradient. The larger the size in concentration gradient (difference in concentration) the faster the rate of diffusion. Hopefully that answered your question.
