Agreed

Thanks so much. This was very nearly going to be a wasted day(!)

Do you think there's an good way of incorporating variables like temp and volume of water?

Wow. Thanks

For this project, I have to go beyond what I know

If I integrate, I get c(t)=kt(100-y). I already have a c term. So is y the same thing? Thanks

Thanks, will look at it. What is y? Just a constant?

Not sure what that means, but, ok

I've been sitting here all day, not really sure where to go (well, I have a few ideas), but are you sure there isn't anything else you know of? It doesn't have to be simple

Yeah, I;m talking about the water's conc

Ah, I see, but having second thoughts, I don't thing it will work because it models a drop in concentration, whereas diffusing tea would result in conc increasing, and thereafter plateauing, right?

I'm in high/secondary school, so I'm know expert in solving, but I know what it involves. Anyway, I had considered that, but would it not just give something of the form c(t)=c(0)*e^(-kt)? Or are you saying that k is a function of all of my other variables (temp, volume..)?

I've done some research, and I've looked at the derivation of the diffusion equation, but I don't want to reproduce even a more simple version of it. I'd like something that can I do almost exclusively myself. The point of this is not to plot some graphs, and extract some line of best fit or...
