Learning Objectives
- Understand the three states of water: solid (ice), liquid (water), and gas (water vapour).
- Explore the processes of melting, freezing, evaporation, and condensation as methods of converting water between its states.
- Investigate the process of evaporation and identify factors that increase its rate, such as temperature, wind, and surface area.
- Examine the process of condensation and how it leads to the formation of water droplets on surfaces.
- Describe the water cycle and its components: evaporation, condensation, and precipitation.
- Explain the cooling effect of evaporation and its practical applications, such as using earthen pots to cool water.
- Identify factors affecting the rate of evaporation, including temperature, humidity, wind speed, and surface area.
- Discuss the role of dust particles in cloud formation and how they serve as surfaces for water vapour to condense.
