Answer 1

The question relates to conducting a scientific investigation in Chemistry to examine how the properties of substances are related to the electrical forces within them. The answer provides a framework for collecting qualitative and quantitative data, designing an experiment, and how to record and analyze findings correctly.

Step-by-step explanation:

The question involves setting up and conducting a scientific investigation in the field of Chemistry to explore the relationship between the properties of substances and the electrical forces that hold those substances together. This process will involve both qualitative and quantitative observations, forming a hypothesis, designing an experiment, and collecting data systematically.

For Step 1, you would need to decide on the types of data you plan to collect, which would include observations about the physical state, melting point, and color changes of various substances. You would also measure quantitative data like temperature changes, electrical conductivity, and mass. You would set up a table with headings such as Substance, Temperature (°C), Mass (g), Electrical Conductivity, physical state, and any other measured properties relevant to your experiment.

In Step 2, you will list detailed steps starting from setting up your experimental apparatus to how you will manipulate your independent variable and measure your dependent variable. This stage also involves sketching your experimental setup to visualize the process.

Upon running your experiment in Step 5, you would record all data and observations under the given headings. In the analysis, a graph could be plotted, for example, showing temperature changes against electrical conductivity to analyze the correlations between them. You might notice trends such as a certain substance changing its conductivity more drastically than others, which can point to different electrical interactions at the molecular level, especially at points of phase transition.

Finally, the scientific method emphasizes replicability, so the experiment should be designed for others to repeat. Descriptive and detailed recording of methods and observations aids in this process and contributes to the overall scientific understanding of the phenomena being studied.
