1.3 Physical and Chemical Properties
A physical change is a change in the state or properties of matter without any accompanying change in its chemical composition (the identities of the substances contained in the matter). We observe a physical change when wax melts, when sugar dissolves in coffee, and when steam condenses into liquid water ( Figure 1.18 ).

Fundamentals of froth flotation | ChemTexts
Froth flotation is one of many techniques used in the mineral processing industry to separate minerals. A discussion of all of them would be beyond the scope of this article. It is, however, important to mention that mineral separation methods rely on differences in various physical and chemical properties of minerals.
Physical Properties: Significance, Importance and examples
Scientists use them to determine what a substance is and how it acts. Examples of physical properties include boiling point, color, density, and conductivity. Physical properties are important for science. They help us study and identify things. We'll learn more about them and how they help us understand materials.

1.3: Physical and Chemical Properties
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, and many other types of reactivity. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 1.3.2 1.3. 2 ).

1.4: Classification and Properties of Matter
Physical properties are characteristics that describe matter. They include characteristics such as size, shape, color, and mass. Many of these properties can be quantitative in nature. For example, quantitative physical properties of water would be the boiling point (100 °C / 212 °F) and melting point (0°C / 32 °F).
3.6: Changes in Matter
Color changes indicate chemical change. The following reaction occurs: Fe +O2 → Fe2O3 Fe + O 2 → Fe 2 O 3. Physical: because none of the properties changed, this is a physical change. The green mixture is still green and the colorless solution is still colorless. They have just been spread together.
