The goal is for students to begin thinking about water, or any substance, on the molecular level and to conclude that water molecules must be attracted to one another. The effect on temperature on gas pressure can be measured by putting a flask of dry air in a water bath with a thermometer, and measuring the pressure with a pressure gauge at different temperatures. 2 The properties of a substance depend on what its particles are like, how they move and how they are arranged. A. Biological molecules - GCSE Biology (Single Science) Revision - BBC Bitesize. They have little curved motion lines to show that the molecules are moving. It also takes up space in the bucket. If a gas is allowed to cool, particles slow down and bonds reform to make a liquid (condensing) and if the liquid cools enough it turns to a solid (freezing). Instead, allow the color to slowly mix into the water on its own. Solids cannot be compressed or squashed because the particles are close together and have no space to move into, Liquids flow and take the shape of their container because the particles can move around each other.Liquids cannot be compressed or squashed because the particles are close together and have no space to move into. CO Carbon dioxide molecules. The quiz will, along with a post-test, serve as a method to determine how much the students have learned after the science unit has been taught. View all updates. We have to imagine these bonds forming and breaking even though we would not see this when using marbles to show the difference between solids, liquids and gases. 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). Use the density equation to work out the density of the liquid. If you leave milk or cream out of the fridge overnight or for a few days, its state of matter changes. fixed shape and positions, vibrate but least energetic.

The particles only vibrate around a fixed point and do not move from place to place, Flow and adopt the shape of the container, The particles can roll over each other because the bonds between them are not strong enough to keep them in a fixed position, The particles are moving quickly in all directions, There are large spaces between the particles, Limitations of the particle theory - Higher, Cells in animals and plants - AQA Synergy, Transport into and out of cells - AQA Synergy, Sample exam questions - building blocks - AQA Synergy, Home Economics: Food and Nutrition (CCEA). Have students draw a model of water on the molecular level on their activity sheet. The energy required by different materials depends on their 'heat capacity' and 'latent heat'. These attractions also help explain the mixing of the color in the water. Changes of state Solid, liquid and gas: - The particle models - Properties of the different states, including density differences. Students should realize that water holds together pretty well because the water molecules are attracted to each other. 0.0 / 5. These molecules may consist of anywhere from 10 to millions of atoms linked together in specific arrays. Observe the properties of flour, a wooden spoon, nuts, water, and oil. They are involved in building organisms from single cells to complex living beings like humans, by interacting with each other. , depending on the type of substance, eg Relativity is a pair of theories that explain space, time and movement. The particle model represents particles by small, solid spheres. Conduction happens whilst a substance is heated, particles will acquire extra energy, and vibrate more. Sign in, choose your GCSE subjects and see content that's tailored for you. For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl, whereas water is always made from twice the number of hydrogen atoms as oxygen atoms, so it is H.
