States Of Matter
Muhtasari
Everything around you, from the water in your glass to the air you breathe and the phone in your hand, exists as a solid, a liquid or a gas. The difference comes down to how particles are arranged, how much energy they carry, and how freely they can move.
In this lesson you will explore the particle model that explains each state, trace the energy changes behind melting, boiling, evaporation and sublimation, and see how diffusion and solubility experiments provide direct evidence for tiny, moving particles. These ideas underpin every reaction you will study later in the course.
Malengo
- understand the three states of matter in terms of the arrangement, movement and energy of the particles
- understand the interconversions between the three states of matter in terms of: - the names of the interconversions - how they are achieved - the changes in arrangement, movement and energy of the particles.
- understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained
- know what is meant by the terms: - solvent - solute - solution - saturated solution.
- know what is meant by the term solubility in the units g per 100 g of solvent
- understand how to plot and interpret solubility curves
- practical: investigate the solubility of a solid in water at a specific temperature
