1.1 understand the three states of matter in terms of the arrangement, movement and energy of the particles




Solids
Particles touch and vibrate around a fixed point. They are in a fixed neat order. Particles have little energy.

Liquids
Particles touch. They are in a random order. Particles move over each other but are always touching at least one other particle. Particles have more energy than a solid but less than a gas.

Gas
Particles are far apart and bounce randomly around the container. Particles are not touching, though they may frequently collide. Particles have a great amount of energy.

1.11 understand how a chromatogram provides information about the composition of a mixture

PAPER CHROMATOGRAPHY - COMPOSITION OF A MIXTURE Diagram Showing the Composition of an Ink using Paper Chromatography COMPOSITION OF A MIXTURE: Chromatograms will Show the Composition of a Mixture as the Different Coloured Substances (Components) will Spread Apart as they will Have Different Solubilities so will Travel at Different Rates A Pure Substance will Only Produce One Spot on the Chromatogram during Paper Chromatography In the Diagram Above, Red, Blue and Yellow are Three Pure Substances, whilst the Sample on the Left is a Mixture of All Three - https://igcse-chemistry-2017.blogspot.ae/search?q=1.11

1.3 understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained

Image
Osmosis : Water particles have   a kinetic energy which allows them to bounce off of each other and mix with the particles of the coloured solution. Eventually the coloured solution will be evenly dispersed  throughout the water, diluting it and making the water turn the colour of the dye. Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a partially permeable membrane. Diffusion: Gas particles have a high kinetic  energy which allows them to bounce off each other and disperse throughout the air, mixing with other particles. eg. the spreading of the scent of perfume through the air Diffusion is the spreading of particles from an area of high concentration to an area of low concentration.
