HEAT AND TEMPERATURE ?

NORMALLY ASKED LATEST QUESTIONS BY ME OR BY STUDENTS ASKED FROM PROFESSORS IN FIELD OF PHYSICS AND THEIR ANSWERS .......





QUESTION 1 : SIR WHAT IS THE DIFFERENCE BETWEEN HEAT AND  TEMPERATURE  YET WE DEFINE THEM SAME WAY ? GIVE EXAMPLE


ANSWER : Heat is the energy flowing between a body and surroundings due to the  differences  of  temperature  . but  TEMPERATURE  is measure of average Kinetic energy of molecules of a body.
EXAMPLE : if we dip a red hot iron ball in the sea , heat will flow from the ball to the water (i.e from higher temperature to lower temperature ) although the amount of internal energy possessed by the ball is very small as compared to immense amount contained in the sea.....
JUST REMIND THESE POINT IN YOUR MIND IT WILL HELP YOU :
