Boyle's Law
Doubling the pressure of a gas reduces the volume of the gas by 1/2, and increasing the pressure of a gas by three times reduces the volume of the gas by 1/3. In 1662, British scientist Boyle (1627-1691) demonstrated through an experiment that the pressure and volume of a gas are inversely proportional at constant temperature, which is called 'Boyle's Law.'
How to calculate the inner pressure of the vessel in this experiment
The inner pressure of the vessel in this simulation can be obtained as follows:
\[ P = \frac{Force}{Area} = \frac{9.8m}{A} (N/m^2, Pa) \]
The standard unit for pressure is N/m² or Pa.
At the earth's surface, standard atmospheric pressure (1 atm) always acts on the container. Since 1 atm is approximately 101,325 Pa, the pressure in the vessel in this experiment can be obtained as follows:
\[ P = 1 + \frac{9.8m}{A\times 101,325} (atm) \]
