The pressure inside a sealed syringe of gas can be increased primarily by decreasing the volume of the syringe.
Decreasing the Volume
According to the provided reference, pressure and volume are inversely proportional. This relationship is described by Boyle's Law. In simpler terms:
- When you decrease the volume of a gas in a sealed container (like a syringe), the gas molecules have less space to move around.
- This leads to more frequent collisions between the gas molecules and the walls of the syringe.
- The increased number of collisions per unit area results in a higher pressure.
The reference states: When the volume of the gas will decrease its pressure will increase as both are inversely proportional to each other. Hence, the pressure inside a sealed syringe of gas increases when the volume of the syringe decreases.
Example
Imagine a sealed syringe with the plunger pulled halfway out. The gas inside has a certain volume. Now, if you push the plunger further in, you're reducing the space the gas occupies. This causes the pressure to rise.
