Multiple Choice

If you heat ice, it ______.

Explanation:
Phase changes happen at specific temperatures when you heat a substance. For ice, the melting point at standard pressure is 0°C, so adding heat makes it change from solid to liquid. That means it melts. If you continue heating, the liquid water would eventually boil into steam, but the immediate result of heating ice is melting. Boiling would require the substance to be liquid first, sublimation is a solid-to-gas change that doesn’t apply under normal conditions here, and sinking isn’t related to heating since ice floats on water.
