Question

Which of the following statements is true about glass?

• A. Arrangement of silicate units is similar to that of liquid state.
• B. Arrangement of silicate units is similar to that of solid state.
• C. It has low viscosity and hence is not a true solid.
• D. It has high viscosity with sharp melting point and hence is a solid.

Answer 1

Answer: (A)

Arrangement of silicate units is similar to that of liquid state.

In glass arrangement of silicates, units are similar to that liquid state because glass is compared to supercooled liquid. This is because of the amorphous state of the glass.
