When ice is heated and turns into liquid water, which change of state is taking place?

• A. Condensation
• B. Sublimation
• C. Melting
• D. Freezing

Answer: (C)

Verified step by step guidance

1. Identify the initial and final states of the substance: Ice is initially in the solid state, and it changes into liquid water, which is the liquid state.
2. Recall the names of phase changes between solid and liquid: When a solid turns into a liquid, the process is called melting; when a liquid turns into a solid, it is called freezing.
3. Understand the other options: Condensation is the change from gas to liquid, sublimation is the change from solid directly to gas without passing through liquid, and freezing is liquid to solid.
4. Match the process described (solid to liquid) with the correct term, which is melting.
5. Conclude that the change of state taking place when ice turns into liquid water is melting.
