Start with hot water and measure the temperature first. Save it.8. Then pour 40 ml into the beaker. You can measure the amount of water used by looking at the meniscus.9. Prepare your stopwatch and drop in the Alka-Seltzer tablet at the same time you started the timer.10. When it has finished dissolving (you can see through the water and there is no more fizzing.), stop the timer and record the results.11. Rinse your beaker thoroughly to wash away any excess powder.12. Repeat steps 7-11 3 more times for reliability. To ensure that the temperature always remains warm, continue to heat the water a little using the heating plate.13. Then repeat steps 7-11 4 times, but this time you don't do it with hot water, you do it with cold water. To keep cold water cold, put ice cubes in the water if it starts to get hot.14. Then repeat steps 7-11 4 more times, but with room temperature water. For room temperature water, simply leave it in the room but try not to change the room temperature.15. Try putting all your recorded data into a table for organization16. Repeat the entire experiment for more reliable data.17. Clean up all your materials and put them all away.Data
