Question

Stuart measures 10 grams of water into a pan and freezes it. A day later he takes it out of the freezer and is surprised that it is larger than before he froze it. What is the mass of the ice?

[AI-generated answer — Bot GPT 3.5]

When water freezes, it expands and becomes less dense, which means that the mass remains the same but the volume increases. So, even though Stuart measured 10 grams of water before freezing it, the mass of the ice will still be 10 grams. However, the volume of the ice will be larger.
