Which example shows the principle of gas solubility?
Answer and explanation
Correct answer: Carbon dioxide dissolved in a cold drink
A cold drink contains carbon dioxide dissolved in a liquid, usually water, so it directly demonstrates gas solubility. The gas is retained more effectively under pressure and is released as bubbles when the pressure falls. Burning wood is a chemical reaction, melting iron is a phase change of a solid, and tearing paper is a physical change involving size and shape, not gas dissolving in a liquid.
