Answer:-
To control water volume in an experiment, use precise measuring tools like graduated cylinders, pipettes, or burettes for accuracy. Always measure at eye level to avoid errors. If adding water gradually, use a dropper or burette for fine adjustments. For automated control, consider using flow meters or controlled dispensers. To maintain consistency, use the same container and temperature since water expands when heated. If evaporation is a concern, cover the container. Double-check measurements before starting, and document the exact volume used. Proper control ensures reliable and repeatable results in your experiment.
