  1. Properties of solids, liquids and gases Can you stick the sheet in please?

  2. Solids?

  3. Solids • Fixed shape • Cannot flow • Difficult to squash • Can’t change volume • Usually “feel” heavy

  4. Liquids?

  5. Liquids • Shape can change • Can flow • Not easy to squash • Cannot change volume • Generally “feel” heavy

  6. Gases?

  7. Gases • Shape can change • Can flow • Easy to squash • Can change volume • “Feel” light

  8. Why?

  9. The particles in a solid are close together. The particles in a solid cannot move around, buttheycan vibrate. The particles in a liquid are also close together. The particles in a liquid also vibrate and can move around. The particles in a gas are far apart. The particles in a gas are moving very quickly. For the same substance (e.g. water), the particles arethe same size in the solid, liquid or gaseous forms.

  10. Melting point of wax?

  11. Table of results

  12. Cooling curves The temperature stays the same during a change of state (melting, boiling etc.) Temp (°C) liquid solidifying Melting point solid Time (mins)

  13. Melting points The melting point is the same as the temperature that a liquid solidifies (turns back into a solid). For example ice melts at 0°C but water also freezes at 0°C.

  14. Pressure in a gas? http://phet.colorado.edu/sims/ideal-gas/gas-properties.jnlp

  15. Pressure in a gas • The particles collide with the sides of the container creating a force we call pressure. http://phet.colorado.edu/sims/ideal-gas/gas-properties.jnlp

  16. Diffusion?

  17. Diffusion? • The random movement of gas partciles cause them to spread out from areas of high concentration to areas of low concentration.
