Which example has particles that can be drawn closer to occupy smaller volume? a. fruit juice b. block of wood c. air inside the syringe d. ice cube
Assuming T is constant, I don't agree with c. I think the answer is d.
The correct answer is c. air inside the syringe.
To understand why, let's break down the options and think about the behavior of their particles:
a. Fruit juice: Fruit juice consists of liquid particles (molecules) that are packed fairly close together but still have some freedom to move around. When you try to draw fruit juice into a smaller volume, the particles might get closer together, but they won't change significantly in size. Thus, fruit juice doesn't occupy significantly smaller volume when drawn into a smaller container.
b. Block of wood: A block of wood is made up of solid particles (atoms) tightly packed together. These particles are held in a fixed position by strong intermolecular forces. Even if you try to compress the block of wood, the particles will remain fixed and won't occupy a smaller volume. So, wood doesn't change its volume when subjected to compression.
c. Air inside the syringe: Air is a gas and is made up of small particles (molecules) that are loosely packed and have high freedom of motion. When air is present inside a syringe, it fills the available space evenly. If you start pushing the plunger of the syringe, you exert pressure on the air molecules, causing them to compress. As a result, the air molecules get closer together, occupying a smaller volume in the syringe. Therefore, the air inside the syringe is an example where particles can be drawn closer to occupy a smaller volume.
d. Ice cube: Ice is the solid form of water. Like wood, the particles in ice are fixed in their positions due to strong intermolecular forces. Even if you try to compress an ice cube, the particles won't move closer together, and the volume occupied by the ice cube will remain the same.
In summary, among the given options, air inside the syringe is the example where particles can be drawn closer to occupy a smaller volume.
