Amorphous and Crystalline Solids starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Amorphous and Crystalline Solids.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A student heats two solids: one melts sharply at 801°C, the other softens gradually between 100°C and 150°C. Which is likely to be crystalline?
A student is given two samples: one is hard and brittle with a definite shape, the other is soft and can be molded. Which is likely to be amorphous?
Describe the difference in the arrangement of particles between crystalline and amorphous solids.
Explain why amorphous solids are called supercooled liquids.
Explain why crystalline solids are anisotropic.
Name two examples each of crystalline and amorphous solids.
State one major difference between amorphous and crystalline solids in terms of melting point.
A scientist finds that a solid sample, when cut, breaks into pieces with smooth, flat surfaces. What does this observation suggest about the type of solid, and why?
Describe how the cooling rate during the formation of a solid affects whether the solid will be crystalline or amorphous.
Explain how the X-ray diffraction pattern of a crystalline solid differs from that of an amorphous solid, and what this reveals about their internal structures.
