Practice and Revision - Properties of Substances
Let us practise and revise what we learned about properties of substances. Substances have distinct properties like state, colour, and solub
Core concept
Substances exist in three states - solid, liquid, and gas - each with distinct properties regarding shape and volume.
How it works
Solubility is a substance's ability to dissolve in a liquid, like sugar dissolving in water, forming a solution.
Why it matters
Some substances conduct electricity or heat well (conductors), while others do not (insulators), an important property for many uses.
Key detail
Understanding these properties helps us select appropriate materials for different purposes, like choosing insulators for electrical safety.
