In thermodynamics, which is that part of the universe which

is selected for investigation.​

Answer 1

Explanation:

The system and the surroundings together make up the universe. There are three types of systems in thermodynamics: open, closed, and isolated. An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air.
