Question

choose the correct answer. which is the best example of an open system on earth? room without windows lake a sealed jar

Explanation:

An open - system exchanges matter and energy with its surroundings. A lake receives water from rivers, precipitation, and loses water through evaporation and outflow. It also exchanges heat with the atmosphere. A room without windows is more like a closed - system in terms of matter exchange (less exchange with outside), and a sealed jar is a closed system as it does not allow matter exchange easily.
