Solids, Liquids And Gases
Muhtasari
Ice, water and steam are all the same substance, yet they look and behave completely differently. The reason lies not in new chemistry but in how the particles are arranged and how fast they move. Once you can picture those particles, the three states of matter make perfect sense.
In this lesson you will meet the kinetic particle theory, which describes matter as tiny particles in constant motion. You will learn how solids, liquids and gases differ in arrangement, movement and spacing of particles, and how heating or cooling drives the changes of state between them.
Malengo
- State the distinguishing properties of solids, liquids and gases.
- Describe the structures of solids, liquids and gases in terms of particle separation, arrangement and motion.
- Describe changes of state in terms of melting, boiling, evaporating, freezing and condensing.
- Describe the effects of temperature and pressure on the volume of a gas.
- [Supplement] Explain changes of state in terms of kinetic particle theory, including the interpretation of heating and cooling curves.
- [Supplement] Explain, in terms of kinetic particle theory, the effects of temperature and pressure on the volume of a gas.
