If a cup of coffee is at 90°c and a person with a body temperature of 36°c touches it, how will heat flow between them? from the hand to the cup from the cup to the hand from the cup to the surrounding air from the hand to surrounding air

From the cup to the hand, because the cup is warmer and the heat has to level out between each other. notice that when you hold a cup of something warm and your hands are cold the cup eventually heats up the hands 

The correct answer to the question is : B) From the cup to the hand.

EXPLANATION:

Before answering this question, first we have to understand the basic law regarding the direction of heat flow.

Heat always flows from a body at high temperature to a body at low temperature irrespective of the amount of thermal energy contained by two bodies as long as no external work is done.

As per the question, the cup is at 90 degree celsius and the temperature of man is 36 degree celsius.

Hence, cup is at higher temperature as compared to man.

Hence, heat will flow cup to hand of man.
