Compare the two beakers that contain water. Which of these statements is NOT true if the beaker on the left represents an open system.
Responses
A Evaporation can occur.Evaporation can occur.
B All the energy remains in the system.All the energy remains in the system.
C Water molecules leave the system.Water molecules leave the system.
D The net movement of molecules is out of the water.
D The net movement of molecules is out of the water.
The statement that is NOT true if the beaker on the left represents an open system is D) The net movement of molecules is out of the water.
To determine which statement is NOT true if the beaker on the left represents an open system, let's analyze each statement:
A) Evaporation can occur: This statement is true. In an open system, such as the beaker on the left, evaporation can occur because water molecules can escape into the surrounding environment.
B) All the energy remains in the system: This statement is generally not true for an open system. In an open system, energy can be exchanged with the surroundings. Some energy may exit the system while other energy may enter the system.
C) Water molecules leave the system: This statement is true. In an open system where the beaker on the left represents an open system, water molecules can escape into the surrounding environment.
D) The net movement of molecules is out of the water: This statement is also true. In an open system, some water molecules can evaporate, leading to a net movement of molecules out of the water.
Therefore, the statement that is NOT true if the beaker on the left represents an open system is B) All the energy remains in the system.
