what is the term for the temperature at
which a liquid changes into a gas?
melting point
freezing point
boiling point
equilibrium point

Explanation:

To solve this, we analyze each option:

• Melting point: Temperature for solid to liquid. Eliminate.
• Freezing point: Temperature for liquid to solid. Eliminate.
• Boiling point: Defined as the temperature where liquid turns to gas (vaporization, specifically boiling). This matches.
• Equilibrium point: Related to balance, not phase change. Eliminate.

Answer:

C. Boiling point
