After reviewing my peers work there was a mix of the hypothesis that said the cold water would freeze faster. Others like myself said that hot water would freeze faster. We also took similar approaches to how experiermnts were done. I saw many people would sue a freezer over leaving the cup outside. Many of us also used faucet water from varying temperatures for our water variables.
Overall it was divided on if hot or cold water froze faster. Many used the mpemba effect to justify their hypothesis and create theories. Many of us made hypothesis that cold water froze faster. An example is Angela Hanson's hypothesis "I immediately came to a hypothesis that cold water has to freeze faster than hot water, it just made sense with the temperatures being so low from already in cold water."
We used a mix of personal experience, background knowledge, and some research to make our hypothesis. We could use them all to compare experiments and ideas. I saw a mix of results of which froze faster but after looking up information and finding an article on medium.com ( https://medium.com/the-physics-arxiv-blog/why-hot-water-freezes-faster-than-cold-physicists-solve-the-mpemba-effect-d8a2f611e853) It is found that hot water freezes faster than cool water more often. But it is not fully concrete and conclusive. Maybe future chemistry students will find the answer.
