Question

What can be said about the mass of a system when a change of state occurs? A) The mass of the system always increases during a change of state. B) The mass of the system always decreases during a change of state. C) The mass of the system remains constant during a change of state. D) The mass of the system varies depending on the type of change of state.

Answer 1

C) The mass of the system remains constant during a change of state.

Step-by-step explanation:

During a change of state (such as melting, boiling, or condensation), the mass of a closed system remains constant. This principle is based on the law of conservation of mass, which states that mass cannot be created or destroyed; it can only change forms or be transferred between components of the system
