Students demonstrate their knowledge of solid, liquid, and gas particles by drawing the particle arrangement for wax vapour, molten wax, and candle wax.
Students are given information and a diagram about a drink bottle overflowing when it had been put into the freezer. Students are asked to explain why this happened and how they could prevent it.
Students draw a graph from some information they are given about the heating of meths in a water bath. Students then explain in terms of particles what is happening for the sloping section and the flat section of the graph.
Students draw diagrams to show the particle arrangement in a solid, liquid, and a gas. Students then describe the differences in arrangement and movement of the particles for each of these states.
Using provided data students decide which of three liquids would freeze if placed in a freezer. Students explain what happens to particles when they freeze and how the level changes due to freezing.
