Have you ever tried to compress the gas in a syringe or in a bicycle pump? Why do you think you can compress the gas? This is a good demonstration for learners to try. Syringes are cheap and available at most pharmacies. Give each learner three syringes. Let them fill on with sand, one with water and one with air.

What happens when you compress air in a syringe?
Answer: The pressure would increase because the volume of space the gas takes up decreases once the bottle is squeezed. There is less room for the gas particles to move around meaning more collisions between the particles occur. What are at least three ways to affect the pressure of a gas in a sealed ?

Robert Boyle, a chemist and physicist from the 17th century, discovered that the volume of gas, meaning how much space it occupies, is related to its pressure—and vice versa. He found that if…

Gas in a syringe being compressed – thermodynamic processes
1. Adiabatic compression (When compressed quickly, there is no heat flow to the environment Q=0) Isochoric with heat loss (The syringe is still compressed, there should be no change in volume) Adiabatic expansion (When the syringe is released, there is work done only)

When you put your finger over the nozzle, you prevent any air from entering or leaving the syringe. Because the air cannot escape from inside the syringe, when you then try to push in the plunger, the air inside the plunger is compressed into a smaller volume. This creates a higher pressure inside the .

When you pull back on a syringe you increase the volume V that the air is distributed in. That causes (approximately) the pressure to go down as 1/V. Of course this pressure isn’t zero, but it is less than atmospheric pressure. Even if there were no air at all in the syringe, starting to reduce the pressure would cause net evaporation from the …

Connect the Gas Pressure Sensor to LabQuest and choose New from the File menu. Step 2. With the 20 mL syringe disconnected from the Gas Pressure Sensor, move the piston of the syringe until the front edge of the inside black ring is positioned at the 10.0 mL mark. Step 3. Attach the 20 mL syringe valve of the Pressure Sensor.

In this Boyle’s law lab, a student fills a 60-mL syringe with the gas to be studied. Students attach a pressure gauge to the syringe (Fig. 1). Slowly push the syringe’s piston into the barrel recording pressure readings at 3-mL intervals until a volume of 30 mL is reached. The compress pressure readings are shown in the data set below.

Assume that the liquid volume in Syringe A is the same as the liquid volume in Syringe B. You need to apply enough pressure on the plunger to overcome atmospheric pressure he syringe. Both the liquid and air have viscous forces that resist flow. Since you have the same amount of liquid in both syringes, then the viscosity of air determines the …

Scuba diving is a form of underwater diving in which a diver carries his own breathing gas, usually in the form of a tank of compressed air. The pressure in most commonly used scuba tanks ranges from 200 to 300 atmospheres. Gases are unlike other states of matter in that a gas expands to fill the shape and volume of its container.
