Re: Keeping coffee hot...



For those who like to appeal to experiment, take a look at the nice
graph on the last page of the winter Vernier newsletter, which was
bound between pages 22 and 23 of the 97 Vernier catalog. The very
experiment Dwight asks about was performed. The coffee with cream
added first is hotter come class time since the delta-T between
beverage and room is smaller, so the rate of heat loss is smaller.
