Heat transferred across a boundary by virtue of temperature difference - Thermodynamics
Q. Heat is transferred across a boundary by virtue of a temperature difference. The heat is transferred, that means- Published on 21 Aug 15a. force transfer takes place
b. energy transfer takes place
c. temperature transfer takes place
d. all of the above
ANSWER: energy transfer takes place
When a system changes its state from state 1 to state 2, the work involved depends upon the path through which the system undergoes change. For consistency with the principle of conservation of energy, some other type of energy transfer along with work transfer must have taken place between the system and surrounding. This type of 'energy transfer' is occurred by virtue of a temperature difference. This energy is called as 'heat'.
