Question

states of matter
which model represents a sample with a definite shape and volume?

Explanation:

Step1: Recall states of matter properties

Solids have definite shape and volume; liquids have definite volume but not shape; gases have neither.

Step2: Analyze each model

• Left: Particles close, ordered (solid? Wait, no—wait, the rightmost? Wait, no, let's check again. Wait, the third model (rightmost) has particles closely packed in a fixed arrangement (like a solid's structure, or wait, no—wait, the first model: particles at bottom, two layers? Wait, no, the rightmost model has particles filling the bottom with a fixed shape (like a solid, or maybe liquid? Wait, no: solids have particles in fixed positions, definite shape. Wait, the rightmost model: particles are closely packed in a row, forming a definite shape (like a solid, where particles are tightly packed and have definite shape/volume). Wait, the middle is gas (particles spread), left maybe liquid (particles at bottom, taking shape of container? No, liquid has definite volume, takes shape of container. Solid has definite shape. So the rightmost model (third one) has particles arranged in a fixed shape (like a solid, with definite shape and volume). Wait, no—wait, the rightmost model: the particles are in a single layer? No, two layers? Wait, the rightmost model's particles are closely packed, forming a definite shape (like a solid, where the arrangement is fixed, so definite shape and volume). The left model: particles at bottom, maybe liquid (takes shape of container's bottom, definite volume, not shape). Middle: gas (spread, no definite shape/[SSE Completed, Client Connection Error][SSE onError error]
