(a)
Interpretation:
The three ways by which internal energy can be increased of an open system has to be explained.
Concept Introduction:
The regions of interest in which the reaction are taking place are considered as the system whereas everything else is said to be surrounding. The system is said to be open system which can exchange both matter and the energy with the surroundings. The system is said to be closed system when it can exchange the energy with the surroundings but cannot exchange the matter.
(b)
Interpretation:
The method which is used to increase the internal energy of a closed system has to be explained.
Concept Introduction:
Same as part (a).
(c)
Interpretation:
The method which is used to increase the internal energy of an isolated system has to be explained.
Concept Introduction:
Same as part (a).
