Make a list of physical properties and physical changes.
Sure! Here’s a list of physical properties and physical changes:
### Physical Properties
1. **Color** - The hue or shade of a substance.
2. **Melting Point** - The temperature at which a solid turns into a liquid.
3. **Boiling Point** - The temperature at which a liquid turns into a gas.
4. **Density** - Mass per unit volume (e.g., grams per cubic centimeter).
5. **Volume** - The amount of space occupied by a substance.
6. **Mass** - The amount of matter in an object, usually measured in grams or kilograms.
7. **State of Matter** - Solid, liquid, gas, or plasma.
8. **Solubility** - The ability of a substance to dissolve in a solvent (e.g., water).
9. **Conductivity** - The ability of a substance to conduct electricity or heat.
10. **Texture** - The feel or appearance of the surface of a substance.
11. **Luster** - The way a surface reflects light (e.g., shiny or dull).
12. **Malleability** - The ability of a substance to be hammered or rolled into thin sheets.
13. **Ductility** - The ability of a substance to be stretched and drawn into wires.
14. **Hardness** - Resistance to scratching or deformation.
15. **Odor** - The scent or smell of a substance.
### Physical Changes
1. **Melting of Ice** - Ice turns into water upon heating.
2. **Boiling of Water** - Water vaporizes into steam when heated.
3. **Dissolving Sugar in Water** - Sugar molecules disperse in water.
4. **Breaking Glass** - The glass fragments do not change its chemical composition.
5. **Chopping Wood** - The wood is physically altered but remains wood.
6. **Mixing Sand and Salt** - The individual particles retain their properties.
7. **Evaporation of Water** - Water changes state from liquid to gas.
8. **Condensation of Water Vapor** - Water vapor turns into liquid upon cooling.
9. **Sublimation of Dry Ice** - Dry ice changes directly from solid to gas.
10. **Freezing of Water** - Water turns into ice when cooled.
11. **Crushing Cans** - The shape changes without altering the material.
12. **Inflating a Balloon** - The shape changes without changing the material.
13. **Bending Metal** - The metal is shaped but retains its properties.
14. **Mixing Ingredients in Cooking** - Ingredients physically combine but do not undergo chemical changes.
15. **Color Change (in some cases)** - Color changes that do not involve a chemical reaction, such as in making a fruit salad where the appearance changes but chemical composition remains the same.
These lists are fundamental in understanding the properties of materials and the processes that affect them.
