Can Someone Please answer this, I need help.
Observation: I am in the lab timing how long it takes to boil 100 mL of water in a beaker over a Bunsen burner. I observe it takes 5:15 mins to boil the water. I want to get the most accurate answer possible so I repeat the test making sure everything is the same. This time it takes 7:05 mins to boil the water. I think this is unusual so I repeat the experiment a third time and it takes 5:20 mins.
What could we infer about the differences in the times observed?
