It seems that there is some confusion about whether salt water or plain water boils faster. To get a definitive answer for your science fair project, here are some steps you can take:
1. Define your hypothesis: Decide whether you believe salt water will boil faster or slower than plain water based on your initial observations or research.
2. Conduct an experiment: Set up a controlled experiment to compare the boiling times of salt water and plain water. Use identical containers and heat sources for both samples.
3. Measure and record: Start the heating process for both the salt water and plain water samples at the same time. Use a thermometer to measure the temperature over time, and record your observations.
4. Analyze your results: Take note of when each sample reaches its boiling point. Calculate the average boiling time for each sample and compare the results.
5. Draw a conclusion: Based on your experiment, determine whether the data supports your hypothesis or not. Consider any potential sources of error and provide explanations for your findings.
Remember, it's important to gather data through experimentation rather than solely relying on anecdotal or conflicting information from others.
