Without viewing the specific images, I can provide general guidance on the types of changes that might occur in a beaker.
- Phase change (A) refers to changes involving a transition between solid, liquid, and gas states (e.g., melting, freezing, evaporation).
- Volume change (B) typically refers to alterations in the amount of space the substance occupies, which may or may not indicate a physical or chemical change.
- Physical change (C) involves changes that do not alter the chemical composition of the substance (e.g., dissolving, change in state).
- Chemical change (D) results in the production of new substances with different properties (e.g., burning, rusting).
If the change in the beaker resulted in a new substance being formed, you would choose D. Chemical change. If the substances were the same but only their state or appearance changed, you would select A. Phase change or C. Physical change. If the volume of the substance altered but its composition remained the same, it would be B. Volume change.
Without additional information about the specific changes observed in the beaker, it's challenging to determine the correct answer. If you could describe what was shown in the images, I would be happy to assist you further!
