Answer:

Step-by-step explanation:

Physical properties are characteristics of matter not associated with a change in chemical composition. Identity of the molecules do not change. A physical change is a change in state without changing the composition (e.g., melting wax, freezing water, grinding solids into powders). Examples: density, color, melting and boiling points, evaporation, odor, taste, hardness, conductivity.

B. Honey dissolving in tea would be a physical change. The honey is not changing chemically but physically as it dissolves in the hot tea.
