IOM 2019, Експеримент — Задача 7. Exercise 2.1: Measuring the temperature dependence of pressure in humid flask
The 4th International Olympiad of Metropolises — Carbon Dioxide Solubility in Water
Recommendations Regarding the Experiment
There are two long exercises in the proposed experiment. Exercise 1.5 and exercise 2.1 in total may take more than three hours to complete. Consider this fact when allocating time and responsibilities to the participants during the experiment.
Условие
Part 2: Solubility-Temperature Relationship
Pour 30 ml of plain water into one of the flasks. Close the flask with a thermometer plug. Place the flask in water at room temperature. Wait a few minutes and connect a manometer to the flask. Wait until pressure in the flask stops changing. Write down the manometer reading and the water temperature in the box. Transfer the flask to the water bath. Completely immerse the flask in hot water by placing it inside a metal cylinder with holes, and secure it with the support stand. Wait until a thermal equilibrium is established; record the pressure in the flask and the water temperature in the water bath.
Решение
Exercise 2.1
Temperature of water in the box:
Temperature of water in the water bath:
Manometer reading at room temperature: –0.2 mmHg
Manometer reading corresponding to the pressure in the flask placed in the water bath: mmHg
