Question

HELP!!!! A glass flask containing 100 milliliters of water is sealed with a rubber stopper and placed on a burner. After a while, gas condenses on the inside surface of the flask near the stopper. What type of system is this an example of? A closed system, because energy can enter or leave the container, but the water molecules cannot. An open system, because heat and the water are both being exchanged between the container and the surroundings. An isolated system, because heat and matter can enter but cannot leave the system. An isolated system, because energy can enter or leave the system, but matter can only move in one direction.

Answer 1

Answer: A closed system, because energy can enter or leave the container, but the water molecules cannot

Explanation:

Open system: In this system energy and matter both have access to their surroundings beyond the boundaries of system. .

Closed system :In this type system only energy has an access to its surroundings beyond the boundaries of system but not matter.

Isolated system:In this type system exchange of both energy and matter are restricted to move outside the boundaries of system.

According to question, the system given is a closed system because energy is transferred from the burner to glass flask and from the glass flask to the water (matter). But water molecules are only getting condensed on the inside surface of the flask that is exchange of matter beyond the boundaries of the system is restricted. Hence, closed system ,A closed system, because energy can enter or leave the container, but the water molecules cannot.
