Explanation:
The experiment is performed at a constant atmospheric pressure. The experiment proceeds by placing an empty flask in a boiling water bath. As the temperature increases, the air inside the flask expands. Afterwards, the gas is cooled in a water bath by maintaining the amount of the air in the flask constant.

Explanation:
From the table we see that the speed of sound in air at 20 °C is 343 m/s. Knowing this we devise the following reasoning:
if the sound travel through the air 343 meters in 1 second
then the sound travel through the air X meters in 2.38 seconds
X = (2.38 × 343) / 1 = 816.35 meters
