Question

Show that in an isolated system, energy can be transformed from one form to another, but cannot
be destroyed using a thermodynamic approach. Explain briefly what happens in an open system.

Answer 1

Explanation:

According to first Law of thermodynamics, in an isolated system, energy can neither be created nor destroyed, though it can change its form from one to the other. This is becasue the system has no connection with the outside world but in case of an open system, energy can escape or interchange. Hence the statement does not remain valid for an open system
