A teacher did an experiment to show the movement of particles in solids, liquids, and gases. The experimental set-up is shown below:
A glass box is shown. Small spheres are shown inside the box taking up half of the space in the box. A blow dryer is shown below with its mouth fitted inside a circular hole on the middle of the top surface of the glass box.
The dryer speed can be adjusted at low, medium, and high to represent each state of matter. Which combination of the state of matter and the corresponding dryer speed is correct?
liquid = low; solid = medium; gas = high.
solid = low; liquid = medium; gas = high.
liquid = low; gas = medium; solid = high.
gas = low; liquid = medium; solid = high.
The correct combination of the state of matter and the corresponding dryer speed is:
liquid = low; gas = medium; solid = high.
The correct combination of the state of matter and the corresponding dryer speed is:
liquid = low; solid = medium; gas = high.
To determine the correct combination of the state of matter and the corresponding dryer speed, we first need to understand the behavior of particles in each state.
In a solid, the particles are tightly packed together and vibrate in fixed positions. They have the least amount of energy and thus have the least amount of movement.
In a liquid, the particles are close together but are able to slide past each other. They have more energy than particles in a solid, allowing them to move more freely.
In a gas, the particles are far apart and move freely in all directions. They have the most energy and the highest amount of movement.
Now, let's consider the experimental setup. The blow dryer is used to represent each state of matter. The speed of the blow dryer can be adjusted to simulate the movement of particles in different states.
The correct combination of the state of matter and the corresponding dryer speed can be determined by matching the behavior of the particles to the appropriate state of matter.
Based on the descriptions provided, we can eliminate options that do not align with the behavior of particles in each state:
- Option 1: liquid = low; solid = medium; gas = high. This is incorrect because the particles in a solid should have the least movement, which would correspond to a low dryer speed.
- Option 2: solid = low; liquid = medium; gas = high. This is also incorrect because the particles in a solid should have the least movement.
- Option 3: liquid = low; gas = medium; solid = high. This is incorrect because the particles in a liquid should have more movement than the particles in a solid.
- Option 4: gas = low; liquid = medium; solid = high. This is the correct combination. The particles in a gas have the highest amount of movement, which should correspond to a high dryer speed. The particles in a liquid have less movement than a gas, but more than a solid, which aligns with a medium dryer speed. The particles in a solid have the least movement, which corresponds to a low dryer speed.
So, the correct combination is gas = low; liquid = medium; solid = high.
