Study Notes

Physical Nature of Matter

Matter is defined as any substance that has mass and volume and can be perceived by senses.
Experimental study shows that matter is made up of tiny particles that can divide into smaller particles.

Characteristics of Particles of Matter

Particles of matter have interparticle spaces between them.
Particles of matter are in continuous motion due to kinetic energy, and the motion increases with temperature.
Particles of matter have interparticle force of attraction that keeps them together.

States of Matter

Solid State

Has definite shape and volume
Mostly incompressible and rigid

Liquid State

Has indefinite shape and definite volume
Mostly incompressible and has fluidity

Gaseous State

Has indefinite shape and volume
Easily compressible and has fluidity

Interconversion of States of Matter

Interconversion can be done by changing temperature or pressure.
Decrease in temperature can cause deposition (gas to solid).
Increase in temperature can cause sublimation (solid to gas).
Increase in pressure can decrease interparticle space.

Evaporation

Evaporation is the process of converting a liquid into a gas at any temperature below its boiling point.
It is a surface phenomenon, unlike boiling which is a bulk phenomenon.
Factors affecting evaporation include:
- Temperature: increase in temperature increases the rate of evaporation
- Humidity: increased humidity decreases the rate of evaporation
- Wind speed: increased wind speed increases the rate of evaporation
- Surface area: increased surface area increases the rate of evaporation
