Question

b) When you put a spoon full of ice-cream in your mouth, you feel cold on
your tongue. What is the mode of heat transfer between the ice-cream
and your tongue?

c) Your mother asks you to finish the glass of hot milk before you go to
play. You want to finish it fast because your friends are calling for you.
But the milk is too hot. Which method of cooling will you use and why?

Please answer both.

Answer 1

Answer:

a.There is a temperature difference between the tongue and the lolly so heat energy flows from the warm tongue into the cold ice lolly. This heat transfer means the ice lolly melts as it gets warmer and the warm part of the tongue touching it gets cooler.

Answer 2

Answer:

B) Convection

C) transfer the just boiled milk into a wide mouthed vessel. If keeping under the fan was possible then turn the fan on at full speed and keep the vessel directly underneath. If fan wasn't an option, then keep the vessel in cold water so that the heat transfer takes place and cools the milk faster.
