Question

chemical and physical properties
which image(s) shows a physical property? choose all that apply.
a i
b ii
c iii
d iv
e v

Explanation:

To determine which images show physical properties, we analyze each:

• Image I (scale) likely measures mass (a physical property, no chemical change).
• Image II (metal and wood) shows physical appearance/state (physical property).
• Image III (ice) shows phase change (physical, no new substance).
• Image IV (fire) involves combustion (chemical change, chemical property).
• Image V (solution with key) – if it's solubility or density (physical, no chemical reaction). Wait, but typically: Physical properties are observed without changing substance identity (mass, appearance, phase, density, solubility). Chemical properties involve reactions (like burning in IV, or maybe V if it's a chemical reaction, but likely I, II, III are physical. Wait, maybe the options: Let's re - check. Physical properties: mass (I), appearance (II), phase (III). IV is fire (chemical, combustion), V – if it's a chemical reaction (like key reacting, but maybe not). So A (I), B (II), C (III) are physical. Wait, but the options are A: I, B: II, C: III, D: IV, E: V. So the correct ones are A, B, C (assuming I is mass (physical), II is physical appearance, III is phase change (physical). IV is chemical (fire), V – if it's a chemical reaction (like key dissolving via reaction, but maybe not. So the answer should be A, B, C.

Answer:

A. I, B. II, C. III
