• A. When the state variables remain constant throughout the system.
• B. When the state variables varies throughout the system.
• C. When the system variables remain constant throughout the system.
• D. When the system variables varies throughout the system.

Answer 1

The correct option is A When the state variables remain constant throughout the system.

A system is said to be in a state of thermodynamic equilibrium when the state variables remain constant throughout the system, i.e., state variables do not change with time and space.
