I pour a cup. It's too hot and too weak. With chopsticks I remove the bag from the pot and dunk it repeatedly in my cup. Will my tea cool faster if I dunk up and down rapidly, or pause several seconds between immersions? --rwg
This is the type of question the I asked (and got asked) as a student. So I have a go.
Assumptions: The dipping goes in negligible time and the bag gets the temperature of the tea in negligible time.
Then the high-frequency method cools faster as the heat flow is governed (linearly) by the temperature difference.
By my assumptions you increase the surface and it is of tea temperature. The "slow" approach would allow a part of the surface be colder (thus less heat flow).
Realistically the vaporization drives much more than linearly and that should make the "fast" method even better.
Amirite?
