Why are open systems harder to study than closed systems? (Engineering and Technology)

The reason open systems are harder to study than closed system is because an open system introduces complexities that obscures the definition of the parameters that influence the given phenomenon being studied

Explanation:

A closed system is a system that is isolated from the environment and there are no introduction or removal of any quantity or attribute to the system, while an open system is one that allows entry or exit of a quantity or a number of quantities or attributes, into and out of the system

Therefore;

A closed system is a controlled system and can therefore be easily monitored such that the effects of treatments applied to the system can be more accurately measured

For an open system, however, the number of variables inputs that results in the outputs of the system are more or less partly controlled, thereby limiting the precision and accuracy of the conclusions drawn from the experimental observations.
