You're on a roll — here are the answers to the questions. 1. Put the correct labels to processes represented by the numbers 1-6 1. Freezing (Liquid to Solid) 2. Melting (Solid to Liquid) 3. Deposition (Gas to Solid) 4. Sublimation (Solid to Gas) 5. Evaporation or Boiling (Liquid to Gas) 6. Condensation (Gas to Liquid) 2. Riaan put 3 litres of water into a kettle and started heating the water until it boils. He then forgot to use the water but when he measured the volume of the water in the kettle it was now less than 3 litres. Explain to him by also referring to the diagram what could have happened to the water. When Riaan heated the water until it boiled, some of the liquid water changed into a gaseous state (steam) and escaped from the kettle. This process is represented by arrow 5 in the diagram, showing the change from liquid to gas. As the water turned into steam, the total volume of liquid water remaining in the kettle decreased, resulting in less than 3 litres. 3. Upon arrival at Giyani, Kgaugelo wanted to drink water but the water was too warm for her to drink. What do you think she should do to the water? Kgaugelo should cool the water down. She could do this by adding ice cubes to it, or by placing the water in a refrigerator or freezer. 4. What will she be doing to the temperature of the water? She will be decreasing the temperature of the water. Drop the next question.
