WebDiagram of apparatus as Dumas described it. Put a boiling stone in the water bath too (but you don't have to know its mass). Keep the flask slightly tilted; it will be easier to notice when the liquid disappears. Keep as much of the flask under water as possible. Measure water bath temperature and atmospheric pressure Heat the water bath gently. WebMay 20, 2024 · The main purpose of a lab report is to demonstrate your understanding of the scientific method by performing and evaluating a hands-on lab experiment. This type of assignment is usually shorter than a research paper. Lab reports are commonly used in science, technology, engineering, and mathematics (STEM) fields.
