- recall that when a substance is not undergoing a state change, a change in its internal energy will result in a change in temperature,
- recall that when a substance is undergoing a state change, a change in its internal energy will not result in a change in temperature,
- interpret graphs and tables of temperature against time for substances and identify the temperatures at which state changes occur,
- describe in approximate terms how particles are arranged in solids, liquids, and gases.
