Question 1:

Which of the following statements is true about the arrangement of particles in a solid state?

A) The particles are closely packed in a regular arrangement
B) The particles are loosely packed and have significant empty space
C) The particles are free to move around randomly
D) The particles are in a gaseous state

Show Answer

Explanation: The correct answer is A) The particles are closely packed in a regular arrangement. In the solid state, the particles are closely packed together in a regular pattern or lattice structure. This arrangement gives solids their definite shape and volume.

Question 2:

Which of the following properties is characteristic of solids?

A) Definite shape and volume
B) Indefinite shape and definite volume
C) Indefinite shape and volume
D) Definite shape and indefinite volume

Show Answer

Explanation: The correct answer is A) Definite shape and volume. Solids have a definite shape and volume due to the strong intermolecular forces and closely packed arrangement of particles.

Question 3:

Which of the following describes the motion of particles in a solid state?

A) Vibrational motion around fixed positions
B) Random translational motion
C) Rapid movement with large distances between particles
D) Constant expansion and contraction

Show Answer

Explanation: The correct answer is A) Vibrational motion around fixed positions. In the solid state, the particles vibrate around their fixed positions due to the strong intermolecular forces that hold them together. This vibration is responsible for the rigidity and stability of solids.

Question 4:

Which of the following is an example of a crystalline solid?

A) Glass
B) Rubber
C) Plastic
D) Diamond

Show Answer

Explanation: The correct answer is D) Diamond. Diamond is an example of a crystalline solid. Crystalline solids have a highly ordered and repeating three-dimensional arrangement of particles, which gives them well-defined crystal structures.

Question 5:

Which of the following is NOT a property of solids?

A) High density
B) Low compressibility
C) Definite melting point
D) Variable shape

Show Answer

Explanation: The correct answer is D) Variable shape. Solids have a definite shape and do not easily change their shape under normal conditions. High density, low compressibility, and a definite melting point are all properties of solids.
