Chapter 12: Problem 53

Define phase change. Name all possible changes that can occur among the vapor, liquid, and solid states of a substance.

Short Answer

Expert verified
Phase change refers to the alteration of a substance from one state of matter to another, i.e., solid, liquid, or gas. The six possible phase changes are Melting, Freezing, Vaporization, Condensation, Sublimation, and Deposition.

Step by step solution

01

Define Phase Change

Phase Change is a term used to describe the transformation of a substance from one state of matter (solid, liquid, gas) to another. During a phase change, the physical properties of the substance alter, but the chemical properties remain the same.
02

Explaining the Possible Changes

There are six possible changes or transformation that can occur among the vapor, liquid, and solid states of a substance. These are:1. Melting: This is the transition from solid to liquid.2. Freezing: This refers to the change from liquid to solid.3. Vaporization: This is a change from liquid to gas and can occur via boiling or evaporation.4. Condensation: This is the change from gas to liquid.5. Sublimation: This refers to the transition from solid directly to gas, skipping the liquid state.6. Deposition: This is the change from gas directly to solid, bypassing the liquid state.
