Question

the following illustrations represent different states of the substance oxygen, o₂, at the particulate level. classify each as solid, liquid, or gas. use the references to access important values if needed for this question. references previous page 4 of 19 next

Explanation:

Step1: Recall particle - arrangement in states

In a solid, particles are closely packed in an orderly manner. In a liquid, particles are close together but can move past one another. In a gas, particles are far apart and move freely.

Step2: Analyze top - image

The particles in the top image are closely packed in an orderly arrangement, so it represents a solid.

Step3: Analyze middle - image

The particles in the middle image are close together and can move past one another, so it represents a liquid.

Step4: Analyze bottom - image

The particles in the bottom image are far apart and move freely, so it represents a gas.

Answer:

Top: Solid; Middle: Liquid; Bottom: Gas
