Respuesta :
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.
The heat flows from the higher temperature to the lower temperature.
The heat transfer between cup of coffee and body is from cup to the hand.
Thus the option B is the correct option.
What is heat transfer?
The heat transfer is the transfer of thermal energy due to the temperature difference.
The heat flows from the higher temperature to the lower temperature.
Given information-
The temperature of the cup of coffee is 90 degree Celsius.
The temperature of the body is 36 degree Celsius.
The flow of heat has to be find out.
As in the given case the cup of coffee is 90 degree Celsius whereas,
the temperature of the body is 36 degree Celsius.
Thus the value of temperature of the cup of coffee is greater than the value of temperature of the body.
[tex]90^oC>36^C[/tex]
It is known that the heat flows from the higher temperature to the lower temperature. Therefore the heat between the cup of coffee and body is transferred from the cup of coffee to the body.
Thus the heat transfer between cup of coffee and body is from cup to the hand.
Thus the option B is the correct option.
