please help me with this challenge question, as i don't quite understand it.:
Yolanda makes this hypothesis: "If salt is added to water, then the water will boil at a lower temperature." She sets up and experiment to test her hypothesis, but discovers that it actually takes more heat to bring the saltwater to the boiling temperature. Her lab partner, Kevin says" Your hypothesis was wrong--no good at all!"
DO YOU AGREE OR DISAGREE WITH KEVIN AND WHY???
please , help me...
This site may help you figure it out.

To answer the question of whether you agree or disagree with Kevin, we need to understand the difference between a hypothesis and a conclusion in an experiment.
Hypothesis: A hypothesis is an educated guess or prediction about the relationship between variables in an experiment. It is based on prior knowledge, observations, and background information. Hypotheses are often formed before conducting an experiment and are used to guide the research.
Conclusion: A conclusion is a statement that summarizes the results of an experiment, based on the data obtained. It is the final step in the scientific method and represents a conclusion drawn from the evidence collected during the experiment.
In this scenario, Yolanda made a hypothesis stating that if salt is added to water, then the water will boil at a lower temperature. However, during the experiment, she found that it takes more heat to bring the saltwater to the boiling temperature.
Based on this information, we can conclude that Yolanda's hypothesis was incorrect. The evidence collected from the experiment contradicts her initial prediction. Adding salt to water actually increases the boiling temperature, rather than lowering it.
Therefore, in this case, you would agree with Kevin's statement. Yolanda's hypothesis was proven to be incorrect based on the experimental results.
