what will you measure to record data of the experiment of mixing water and sugar/salt dissolved in hot water?
I would record amount of water, temp, amount of sugar, amount of salt.
To record data for an experiment involving the mixing of water and a substance like sugar or salt dissolved in hot water, you would typically measure the following parameters:
1. Mass or Weight: Measure the mass or weight of the substances used before dissolving them. This can be done using a weighing scale or balance. For accurate measurements, make sure the scale is properly calibrated.
2. Volume: Measure the volume of water used along with the dissolved substance. You can use a graduated cylinder or measuring cup to measure the volume of water. Ensure you read the measurements at eye level for accuracy.
3. Temperature: Record the initial temperature of the hot water and monitor its changes during the experiment. A thermometer can be used to measure the temperature. Insert the thermometer into the liquid without touching the sides or the container.
4. Dissolution Time: Depending on the objective of the experiment, you may also measure the time it takes for the sugar or salt to fully dissolve in the hot water. Start the timer as soon as you begin stirring the mixture and stop it when no solid substance is visible.
Remember to have a clear and organized data recording system, such as a lab notebook or a data table, to record these measurements accurately and systematically.
