Question

Which action would you use to determine the melting point of a substance?
(1 point)
increasing its temperature until it transitions from a liquid to a gas
decreasing its temperature until it transitions from a solid to a liquid
increasing its temperature until it transitions from a solid to a liquid
decreasing its temperature until it transitions from a gas to a liquid

Answer 1

increasing its temperature until it transitions from a solid to a liquid

Explanation: the melting point is the temperature at which a solid becomes a liquid, so you heat the solid until it melts.
