1) In a syringe, what happens to the air paricles when you push the plunger?
2) In a syring, what happens the the air particles in the bubble from the bubble wrap when you pull up the plunger?
3) Are there more air particles in the bubble when it is compressed or when it is expanded?
4) When you push the plunger, are the air particles closer together in the syringe or in the bubble?
5) What is between air particles?
6) What happens to air particles when a volume of air is compressed? When a volume of air expands?
1) When you push the plunger of a syringe, the air particles inside the syringe get compressed. The space inside the syringe decreases, and as a result, the air particles are forced to move closer together.
To understand this concept, you can think of air particles as small individual units with a certain amount of space between them. When you push the plunger, you decrease the volume of the syringe, which means the same amount of air particles now occupies a smaller space. As a result, the air particles are more compressed.
2) When you pull up the plunger of a syringe, the air particles in the bubble from bubble wrap expand. The space inside the syringe increases, allowing the air particles to spread out and take up more space.
By pulling up the plunger, you increase the volume of the syringe, which means the same number of air particles now occupies a larger space. As a result, the air particles in the bubble from bubble wrap expand and become less compressed.
3) When the bubble is compressed, there are more air particles present in the same volume compared to when the bubble is expanded. This is because compression decreases the volume, forcing the same number of air particles to occupy a smaller space. So, by compressing the bubble, the air particles become more densely packed.
4) When you push the plunger, the air particles in the syringe become closer together. This is because pushing the plunger reduces the volume of the syringe, forcing the same amount of air particles to occupy a smaller space. Therefore, the air particles in the syringe are closer together compared to the air particles in the bubble.
5) Between air particles, there is empty space. Despite appearing continuous, air is composed of countless tiny particles, or molecules, with spaces between them. These spaces are what we typically refer to as "empty" or "empty space". So, air particles are not tightly packed together, and there is empty space between them.
6) When a volume of air is compressed, the air particles are pushed closer together, resulting in an increase in pressure. This compression causes the air particles to collide with each other more frequently and with greater force.
On the other hand, when a volume of air expands, the air particles move further apart, leading to a decrease in pressure. This expansion happens because the volume available for the same number of air particles increases, allowing them to spread out. The air particles collide less frequently and with less force, causing a decrease in pressure.
