Part C In this experiment, you’ll perform three trials. Follow these steps to proceed with the first trial: Fill one of the two bowls with very warm water, between 45°C and 49°C (113°F and 120°F). Use the thermometer to measure the temperature of the water in degrees Celsius, and record it in the provided table. Stay safe! To avoid burns, do not use water hotter than 49°C. Fill the other bowl with ice water. The temperature of the water in this bowl should be between 5°C and 10°C (41°F and 50°F). Use the thermometer to measure the temperature of the water in degrees Celsius, and record it in the table. With the bottle uncapped, hold the bottle in the bowl of warm water. The bottle should be mostly under water, but the mouth of the bottle should be above the water so that water doesn’t enter the bottle. Hold the bottle in this position for three minutes, using the stopwatch to track the time. The air inside the bottle will come to the same temperature as the water in the bowl. Cap the bottle tightly, and then remove it from the warm water.
