Answer:
C. a capped soda bottle represents a system that is almost completely closed.
Step-by-step explanation:
C. A Soda bottle with the top on symbolizes an almost closed system.
In a closed system, energy can only be exchanged through heat or work and matter cannot enter or depart. A Coke bottle with the cap on is a good illustration of a closed system because, after the cap is on, no matter can enter or leave the bottle, and the pressure inside the bottle rises as the liquid's carbon dioxide cannot escape.
Steam and water vapor can escape from a partially closed saucepan of boiling water. Due to the possibility of adding or removing water and detergent during the cycle, a washing machine is never fully closed.
