States of Matter (Solid, Liquid, Gas)Quiz - Solve & Score
Q1. A jeweller holds a gold ring that keeps its exact shape and size in any box it is placed in. In which state of matter is this substance?
- A.Liquid
- B.Solid
- C.Gas
- D.Vapour
Answer: B. Solid

Q2. A pharmacist has 192 g of a syrup of density 1.2 g/cm^3. What volume does it occupy?
- A.0.0062 cm^3
- B.160 cm^3
- C.193.2 cm^3
- D.230.4 cm^3
Answer: B. 160 cm^3
Volume = mass / density = 192 / 1.2 = 160 cm^3.
Q3. A student arranges the three states of one substance from the most tightly packed particles to the most loosely packed. What is the correct order?
- A.Solid > Gas > Liquid
- B.Solid > Liquid > Gas
- C.Gas > Liquid > Solid
- D.Liquid > Solid > Gas
Answer: B. Solid > Liquid > Gas
Particle packing is densest in solids, looser in liquids, loosest in gases: Solid > Liquid > Gas.
