What do we call the process of ice changing to liquid water? 5. What do we call the process of liquid water changing to ice? 6. What do we call the process of liquid water changing to water vapour (steam)? 114 Matter and Materials
7. What do we call the process when steam (water vapour) changes to water? 8. Do the particles in the ice change when the ice melts? 9. If ice and liquid water have the same particles, why do ice and liquid water have dierent properties? (Ice is solid and water is liquid.) 10. How can the water particles in ice be made to move freely? (Think of the 'solid' learners. What did we give them to make them move?) KEY CONCEPTS • Matter can exist as 3 states, namely solids, liquids and gases. • The particles in solids are closely packed and have fixed positions. • The particles in liquids are also closely packed but they can move around each other. • The particles in gases have large empty spaces between them.
