Chapter 1: Problem 8

Molten iron cooling to solid iron is an example of (a) sublimation (b) condensation (c) freezing (d) melting

Short Answer

Expert verified
The correct answer is (c) Freezing, as molten iron cooling to solid iron involves the transition from a liquid to a solid state.

Step by step solution

01

Option (a) Sublimation

Sublimation is the process in which a substance changes directly from a solid to a gas without passing through the liquid state. This does not fit our scenario, as molten iron is in a liquid state, and it is turning into a solid state. Therefore, sublimation is not the correct option.
02

Option (b) Condensation

Condensation is the process in which a substance changes from a gas to a liquid state. This does not fit our scenario, as molten iron is initially in a liquid state and it is turning into a solid state, not a gas. Therefore, condensation is not the correct option.
03

Option (c) Freezing

Freezing is the process in which a substance changes from a liquid to a solid state, usually due to a decrease in temperature. This option fits our given scenario, as molten iron is in a liquid state and when cooled, it turns into solid iron. Therefore, freezing is the correct option that describes molten iron cooling to solid iron.
04

Option (d) Melting

Melting is the process in which a substance changes from a solid to a liquid state, usually due to an increase in temperature. This does not fit our scenario, as molten iron is initially in a liquid state and it is turning into a solid state, not the other way around. Therefore, melting is not the correct option. Based on the analysis, the correct answer is: \( \boxed{(c) \text{ Freezing}} \)
