Ms. Natalie Wieland shows the water boiling at room temperature.

To better understand the concept of vapor pressure, Pre-AP Chemistry students challenged the impossible by boiling water at room temperature on Monday, Jan. 23.

“The experiment was very fun,” Atharva Joshi ‘20 said. “It helped me understand vapor pressure by showing me how it works in action.”

In order to accomplish the feat, the students created a vacuum within the flask filled with water. By doing so, the students were able to successfully boil the water at room temperature.

“During the experiment, Ms. Wieland explained the process of the heating curve of water, vaporization, and vapor pressure by taking a glass of water that was only about 30 degrees Celsius and decreasing the atmospheric pressure to make it boil,” Manasi Chande ‘20 said. “It really made me understand the real definition of boiling and how important vapor pressure is in the process.”
