Study Notes
Matter and Its Properties
- Matter is anything that has mass and occupies space.
- The state and properties of matter are influenced by temperature, pressure, and the presence of other substances.
Particles of Matter
- The particles of matter are tiny, indivisible, and indestructible units that make up matter.
- These particles are in constant motion, and their movement increases with an increase in temperature.
Forces Between Particles
- The force that acts between the particles of matter is the intermolecular force.
- This force is responsible for holding particles together and giving matter its shape and structure.
Breaking a Substance
- To break a substance, we need to overcome the intermolecular forces holding its particles together.
- This requires energy, which can be provided through heat, light, or other forms of external energy.
