Coffee

[Cyberus]

Right, you've just made yourself a cup of coffee when the phone rings. You're expecting the call, and know that it'll take 5 mins. In this time, you are worried that your coffee will get cold.
You take milk in your coffee, but you have to make the decision - do you put the milk in now, thus making the coffee cooler and thus meaning there is smaller temperature difference between coffee and the air, or do you think it'll be hotter if you wait until after the call and then put the milk in?



I couldn't resist posting this - its about coffee and its the first post in this forum, woohoo! ;-)

As you probably know, I don't drink coffee often at all, and when I do its without milk... :-)

But as you say, tea's much better.

Everyone knows that coffee drinkers oppress the third world in any case ;-)

Hmph, I put this in the science and technology forum, because it is science - even if I did this problem for GCSE physics when I was fifteen. Booo, I wanted to be the first person to post in the science forum and I thought that this was a nice topic to do it with.

Kenny, it was meant as a rhetorical question.
