Chapter 7. Experiments with Water- Exploring Properties and Phenomena

Introduction: Water is a fascinating substance that exhibits numerous unique properties and can undergo various intriguing phenomena. In this chapter, we will embark on a journey of experimentation to uncover some of the mysteries and characteristics of water. Through hands-on experiments, we will investigate its physical properties, explore its behavior under different conditions, and observe some captivating phenomena associated with water. Let’s dive in!

7.1. The Effects of Temperature on Water Objective: To understand how temperature influences the physical properties of water.

Experiment 1: The Expansion of Water Materials:

Procedure:

  1. Fill the glass jar with water, leaving some space at the top.
  2. Add a few drops of food coloring to make it easier to observe.
  3. Place the thermometer in the jar and record the initial temperature.
  4. Seal the jar and heat it gradually using a heat source (e.g., a Bunsen burner or hot plate).
  5. Continuously monitor the temperature and observe any changes in the water level.
  6. Note down the final temperature and compare it with the initial reading.

Results: As the temperature increases, the water molecules gain energy and move faster, causing the water to expand. This expansion can be observed by the rising water level in the jar.

Conclusion: This experiment demonstrates the expansion of water as the temperature rises, highlighting one of the unique properties of water.

7.2. Surface Tension of Water Objective: To explore the phenomenon of surface tension in water.

Experiment 2: The Paperclip Challenge Materials:

Procedure:

  1. Fill the small bowl with water.
  2. Gently place a paperclip on the surface of the water without breaking the surface tension.
  3. Observe whether the paperclip floats or sinks.
  4. Repeat the experiment by gradually adding more paperclips to see how many can be placed on the surface without sinking.

Results: The paperclip(s) should float on the surface of the water due to surface tension. Several paperclips can be placed without breaking the water’s surface tension.

Conclusion: Water exhibits surface tension, which allows certain objects, like paperclips, to float on its surface. This phenomenon arises from the cohesive forces between water molecules.

7.3. The Freezing and Melting Points of Water Objective: To determine the freezing and melting points of water.

Experiment 3: Freezing and Melting Materials:

Procedure:

  1. Fill the small container with ice cubes.
  2. Place the thermometer in the container, making sure it’s in contact with the ice.
  3. Observe the temperature and record it when the ice starts melting.
  4. Continue monitoring the temperature until all the ice has melted.
  5. Record the temperature when the ice is completely melted.

Results: The temperature at which the ice starts melting is the freezing point of water (0 degrees Celsius or 32 degrees Fahrenheit). The temperature remains constant during the melting process until all the ice has transformed into water.

Conclusion: This experiment helps determine the freezing and melting points of water, providing insight into its phase change behavior.

7.4. Capillary Action in Water Objective: To observe the phenomenon of capillary action in water.

Experiment 4: The Colored Water Rise Materials:

Procedure:

  1. Fill the clear glass with water.
  2. Add a few drops of food coloring to the water and stir gently.
  3. Fold the paper towel or tissue paper strip vertically and dip one end into the colored water.
  4. Observe the water rise along the paper towel or tissue strip.

Results: The colored water rises along the paper towel or tissue strip due to capillary action. This occurs because water molecules adhere to the surface of the paper towel and interact with each other through cohesive forces, causing the water to move upward.

Conclusion: Capillary action is a phenomenon exhibited by water, where it can climb up narrow tubes or spaces against gravity, as seen in this experiment. This property is crucial for various natural processes, such as water absorption in plants.

Conclusion: Through these experiments, we have explored some intriguing aspects of water, including its expansion with temperature, surface tension, freezing and melting points, and capillary action. Water’s unique properties and phenomena make it a captivating subject for scientific exploration, with countless real-world applications. By conducting experiments like these, we can deepen our understanding of water and its role in our daily lives.
