Physics - Temperature Variation in Time
With the option "Cream in the beginning" box checked it'possible to change all the settings to see what will be the final temperature after 5 minutes, depending in the volume of cream added, its temperature and the volume of tea. It is supposed that the initial temperature of Tea is 75 ºC.
With the "Cream in the beginning" box unchecked and "Cream in the end" box checked the cream volume must be set to 0, because it is supposed that the volume is 50 ml and the tea volume is 200 ml (just for comparison purposes with the initial case).
