Study Notes

Temperature and Particle Motion

Particle energy is directly proportional to temperature.
Higher temperatures increase the kinetic energy of particles, causing them to move faster.
Matter undergoes state changes (solid, liquid, gas) due to temperature changes, which is a physical change that does not affect chemical composition.

Particulate Theory of Matter

All matter consists of tiny particles in constant, random motion.
Presence of spaces between particles allows movement, supporting diffusion and osmosis processes.
Forces of attraction between particles vary in strength among solids, liquids, and gases.

Diffusion

Defined as the movement of particles from an area of higher concentration to lower concentration until evenly distributed.
Diffusion occurs due to the constant motion of particles in different concentration gradients.

Osmosis

Water molecules move from areas of high concentration (dilute solutions) to low concentration (concentrated solutions) through a selectively permeable membrane.
Osmosis is a special case of diffusion concerning water movement across membranes with minute pores, allowing only water to pass.

Experimental Evidence

Investigative experiments illustrate diffusion and osmosis using substances like potassium manganate and potato cells.
In diffusion experiments, color spread indicates particle movement confirming the particulate theory.

States of Matter

Three main states: solids, liquids, and gases, differentiated by particle energy, arrangement, and attraction strength.
Solids have tightly packed particles, liquids have more loosely packed particles, and gases have widely spaced particles.

Practical Applications of Osmosis

Sodium chloride (table salt) can control garden pests by creating a concentrated solution that leads to osmosis, causing dehydration in slugs and snails.
Salt and sugar preserve food by withdrawing water from food cells and microorganisms, delaying decay by preventing chemical reactions.

State Changes

Changing states (melting, freezing, boiling, etc.) is caused by temperature shifts, altering particle kinetic energy without changing chemical composition.
Heat removal converts water to ice, illustrating the relationship between temperature change and particle state transition.

Key Physical Properties

Physical properties such as shape, volume, density, and solubility can be measured without altering chemical composition and vary among the three states of matter.
Understanding these properties through the particulate theory helps explain observable phenomena like buoyancy and density variations.
