Answer
Brief Explanations:
In an open - system, matter can be exchanged with the surroundings. Initially, there is 12 grams of ice. If the container is an open system, some of the water can escape as vapor. Option E shows that the total mass of water in the container (8 grams liquid + 4 grams vapor = 12 grams initially) has some of it in the vapor phase, indicating that matter (water vapor) has potentially left or entered the system.
Answer:
E. The container contains 8 grams of liquid water and 4 grams of water vapor.
