Question

1. which of the three states represent a liquid? explain why
2. which of the diagrams represents a solid? explain why
3. if state b is heated, which state would it more closely resemble? explain why!

Explanation:

Question 16

In the particle model of matter, liquids have particles that are close together but can move past each other (not in a fixed, rigid arrangement like solids, nor far apart like gases). Diagram B shows particles that are relatively close but not in a strict, ordered pattern (unlike A, which looks like a solid with fixed positions) and not as spread out as C (which looks like a gas). So B represents a liquid because its particles are close but can move, fitting liquid's properties.

Solids have particles in a fixed, ordered, closely - packed arrangement (they vibrate in place but don't move freely). Diagram A shows particles in a regular, tightly - packed pattern, which is characteristic of a solid’s particle arrangement (unlike B’s more mobile - looking particles or C’s spread - out particles). So A represents a solid.

When a liquid (State B) is heated, it gains energy, and its particles move faster and spread out more, transitioning towards a gas. State C has particles that are far apart and move freely, which is the behavior of a gas. Heating State B (liquid) will cause its particles to gain energy, move more, and spread out, so it will resemble State C (gas) more closely.

Answer:

B represents a liquid. Liquids have particles close (but not rigidly fixed like solids) and able to move past each other; B’s particles are close but not in a fixed pattern, matching liquid behavior.
