Answer: - C. The container contains 8 grams of liquid water and no ice.

Explanations: - In thermodynamics, "An open system is the one that exchanges energy and matter with it's surroundings."

If we look at all the choices then the total mass is 12 grams except for choice C. So, the correct choice is C as the mass in the container remains 8 grams since some of the amount is lost to the surroundings in the form of water vapors.
