Task 2c: Complete the exam question and mark your answers. Atom economy and percentage yield worksheet higher by. These biological molecules are composed of carbon, hydrogen, and oxygen molecules. They vibrate in their fixed positions, not changing shape, so they are the least energetic of the states of matter. The kinetic particle theory of matter is a model that describes the arrangement, movement and energy of particles in a substance. The three states of matter can be represented by the particle model. In a solid, the atoms and molecules are attached to each other. Use the specification to help you. The model can be used to explain the, have a fixed shape and cannot flow, because their particles cannot move from place to place, (squashed), because their particles are close together and have no space to move into, flow and take the shape of their container, because their particles can move around each other, cannot be compressed, because their particles are close together and have no space to move into, flow and completely fill their container, because their particles can move quickly in all directions, can be compressed, because their particles are far apart and have space to move into, Sample exam questions - bonding, structure and matter - AQA, Bonding, structure and the properties of matter, Home Economics: Food and Nutrition (CCEA).

Task 7a: Read through the slides and watch the video, Describe the motion of particles in a gas, Describe the relationship between pressure and temperature, Explain why an increase in temperature leads to an increase in pressure. The flat section of a temperature - time graph shows the melting or boiling point of a substance, as the energy transferred to the substance when it changes state is called latent heat, where the substance doesn't change temperature. Flour can be poured and take the shape of its container, like a liquid, but it also can be picked up and held, like a solid. Explain to students that this is a model of water molecules. New and improved GCSE Science resources and support available. Nucleic acids (DNA and RNA; polymers of nucleotides). If you could count 1 million water molecules every second, it would take about 200 million centuries to count all the molecules in that tablespoon of water.

Water is the only substance where all three states can be readily observed in everyday life: solid water as ice, liquid water in a water fountain, and gaseous water as steam. Adding heat energy to particles either raises the temperature and they move faster, or bonds are broken to change from solid to liquid (melting) or liquid to gas (boiling). Thousands of interactive activities including drag and drop, wordsearches, anagrams and flashcards for GCSE science revision. When you squeezed the drop of water out of the dropper, did the water break apart or did it hold together?
