Q:

Which of the following describes a general solid?

A) Compressible B) Incompressible
C) Fluid D) Semi-compressible
 
Answer & Explanation Answer: B) Incompressible

Explanation: The intermolecular forces of attraction in a solid are very strong, making it incompressible. Gases are highly compressible, while liquids are semi-compressible. Fluid is a property of a substance that can ‘flow’.

Q:

Which type of solid structure melts at a definite, sharp melting point?

A) All types of solids B) No type of solid
C) Amorphous solids D) Crystalline solids
 
Answer & Explanation Answer: D) Crystalline solids

Explanation: Crystalline solids have a perfectly ordered structure which collapses immediately at a specific temperature. Amorphous solids melt over a range of temperatures, not one specific value.

Q:

Amorphous solids are actually supercooled liquids.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: Amorphous solids behave like fluids and flow very slowly under the influence of gravity. Hence, they are said to be supercooled liquids.

Q:

Which of the following is an amorphous solid?

A) Quartz B) Quartz glass
C) Graphite D) Salt (NaCl)
 
Answer & Explanation Answer: B) Quartz glass

Explanation: Quartz glass does not have a perfectly ordered structure, hence it is classified as an amorphous solid. The rest are crystalline solids due to ordered structures.

Q:

Which of the following can be used to describe a crystalline solid?

A) Heterogeneous, anisotropic B) Homogeneous, anisotropic
C) Heterogeneous, isotropic D) Homogeneous, isotropic
 
Answer & Explanation Answer: B) Homogeneous, anisotropic

Explanation: Homogeneity refers to uniformity in composition, which is a characteristic property of crystalline solids. Isotropy is when the values of physical properties do not change with direction throughout the body of the solid. Crystalline solids are anisotropic because the composition of the solid changes with direction, hence the physical properties also change with direction.

Q:

Solid-state is denser than the liquid and gaseous states of the same substance. Which of the following is an exception to this rule?

A) Mercury B) Carbon dioxide (dry ice)
C) Ice D) NaCl
 
Answer & Explanation Answer: C) Ice

Explanation: The density of ice is about 0.92 g/cm³ while that of water is 1 g/cm³. Mercury has density 14.184 g/cm³ as solid and 13.69 g/cm³ as liquid. Carbon dioxide has density 1.56 g/cm³ as solid and 1.10 g/cm³ as liquid. NaCl has density 2.71 g/cm³ as solid and 1.556 g/cm³ in molten state. Therefore only ice has lesser density as a solid than as a liquid.
