Amena Deacribed Her Idea About The Evaporates Of Watershe Think Tha

Amena deacribed her idea about the evaporates of water. She think that water evaporates faster if temperature is in creased. Write a plan for an investigation you could carry out in the school laboratory to test Amena's idea. In your plan you must write: 1. The factor you would change as you carry out your investigation (the independent variable) 2. the effect you would observe or measure as you carry out your investigation (the dependent variable) 3. one factor you would keep the same to help make your test fair.

To test Amena's hypothesis that water evaporates faster at higher temperatures, an experimental investigation can be conducted in a school laboratory setting. The goal of this experiment is to determine the relationship between temperature and the rate of water evaporation, ensuring that the procedure is fair and reliable.

Independent Variable: The temperature of the water. This can be varied by placing the water containers at different temperature levels such as room temperature, heated water bath, or refrigerated environment.

Dependent Variable: The rate of evaporation, which can be measured by recording the change in water level (volume) over a specific period, typically by using a measuring cylinder or weighing the water before and after the experiment.

Control Factors: To ensure a fair test, several factors must be kept consistent across all test conditions. The size and material of the container should be the same to prevent differences in surface area or heat absorption. The initial amount of water used in each container should be identical. The exposure to air, such as the distance from a fan or drafts, should remain constant, and the duration of the experiment should be the same for all trials.

Experimental Procedure:

1. Prepare multiple identical containers filled with the same amount of water.
2. Set each container at different and controlled temperatures—one at room temperature, one in a warm environment, and one in a hot environment, using water baths or heaters where appropriate.
3. Ensure all containers are placed in the same location concerning airflow and light exposure.
4. Start the timer and measure the initial amount of water in each container.
5. Allow the water to evaporate over a fixed period, such as 30 minutes or an hour.
6. At the end of the period, measure the remaining water in each container.
7. Calculate the evaporation rate by subtracting the final water amount from the initial amount, divided by the time elapsed.

Data Analysis: Plot the evaporation rates against the different temperatures to observe the relationship. A trend should emerge showing increased evaporation with rising temperature. Scientific literature supports this, indicating that increased temperature accelerates water molecules' kinetic energy, thus promoting faster evaporation (Tsonis, 2009; Alley et al., 2014).

Conclusion: The investigation will either confirm or refute Amena's idea that increasing temperature increases the evaporation rate of water. If the data support this, it reinforces the understanding of evaporation as a temperature-dependent process. If not, further investigation into other influencing factors like humidity or air circulation may be necessary.
