Describe the processes of condensation, freezing, melting, and evaporation using the provided keywords and definitions.

Here are the answers to your questions:

5. a) Your teacher will hold the sheet of glass or cling wrap above the boiling water.

b) Water droplets will form on the underside of the glass or cling wrap.

c) The boiling water produces hot water vapor. When this hot water vapor comes into contact with the cooler surface of the glass or cling wrap, it loses heat energy and changes back into liquid water. This process is called condensation.

6. a) You can change the water back into ice by cooling it down to its freezing point (0°C or 32°F) or below.

b) This process is called freezing or solidification.

7. Use the words to complete the sentences about change of state in water.

a) Ice melts when it gains heat and forms water.

b) Water evaporates when it gains heat and forms water vapour.

c) Water vapour condenses when it loses heat and forms water.

d) Water solidifies when it loses heat and forms ice.
