what example demonstrates the law of conservation of matter?\na. an echoing shout\nb. sunlight brightening\nc. a bell ringing\nd. candle wax melting
Answer
Brief Explanations:
The law of conservation of matter states that matter is neither created nor destroyed in a physical or chemical change, only transformed.
- Option A (echoing shout) involves sound waves (energy, not matter conservation).
- Option B (sunlight brightening) involves light energy (not matter).
- Option C (bell ringing) involves sound production (energy transfer, not matter conservation).
- Option D (candle wax melting) is a physical change (melting). The wax changes state from solid to liquid, but the total mass of wax remains the same—demonstrating matter conservation (no matter is created or destroyed, just its state changes).
Answer:
D. Candle wax melting
