A process in which a solid changes into a liquid is ___.
deposition
melting
freezing
vaporization
sublimation
condensation
melting
The correct answer is "melting".
The correct answer is "melting."
To understand why melting is the correct answer, let's first go through the process of elimination with the other options:
- Deposition: This is a process in which a gas turns directly into a solid, bypassing the liquid phase. Therefore, deposition is not the process of a solid changing into a liquid.
- Freezing: Freezing is the process in which a liquid changes into a solid. It is the reverse of melting, so it does not involve a solid changing into a liquid.
- Vaporization: Vaporization is a general term that refers to the process of a liquid changing into a gas. This process is the opposite of condensation and does not involve a solid changing into a liquid.
- Sublimation: Sublimation is a phase transition from a solid directly into a gas without passing through the liquid phase. It does not involve a solid changing into a liquid.
From the remaining options, we can see that melting is the only process that specifically describes a solid changing into a liquid. Therefore, the correct answer is "melting."
