A scientist is interested in learning more about water’s phase change properties. The scientist decides to perform an experiment to determine the amount of time it would take to melt ice compared to the amount of time it would take for water to boil
Write a procedure for the experiment. in 6 steps
1. Gather all necessary materials and equipment for the experiment, including ice, a thermometer, a heat source (such as a Bunsen burner or hot plate), a stopwatch or timer, and a container for the ice and water.
2. Set up a controlled environment for the experiment. Ensure the room temperature is consistent and minimize any external factors that could affect the rate of phase change, such as drafts or direct sunlight.
3. Fill the container with a known amount of ice. It is important to measure and record the initial mass or volume of the ice for accurate data analysis.
4. Place the thermometer in the container, making sure it is immersed in the ice. Start the stopwatch or timer.
5. Observe and record the time it takes for the ice to completely melt. Monitor the temperature of the ice-water mixture using the thermometer throughout the process.
6. Repeat the procedure for boiling water. Fill the container with a known amount of water and place it on the heat source. Insert the thermometer into the water and start the stopwatch or timer once again. Monitor the temperature of the water and record the time it takes for the water to reach its boiling point.
Note: To increase the accuracy of the experiment, consider performing multiple trials and calculating the average time for each phase change. Additionally, maintain a constant heat source intensity for boiling water and monitor the temperature regularly to ensure it remains at or near its boiling point.
