Whithin which type of system is neither the total mass nor the total energy conserved ? a. open b. connected c. isolated d. closed

a. open.

Explanation:

Open System:

A system that has external interactions is called an open system. In natural sciences an open system is the one whose border is permeable to both energy and mass. In thermodynamics a closed system, by contrast, is permeable to energy but not to matter.

As there are external interactions, the open system might lose/gain energy as well as matter.
