In general the properties of materials may be divided into three groups.
A) electrical, mechanical, thermal
B) viscosity, density, temperature
C) resilience, toughness, heat capacity
D) none of the above

Question

Quizplus · Accepted Answer

Electrical, mechanical, and thermal properties are the three primary groups of material properties. Viscosity, density, toughness, and heat capacity are all specific properties that fall under one of the primary categories. Choice C includes three specific properties that all fall under the mechanical properties category, and choice B includes viscosity, which is a specific property that falls under the broader category of mechanical properties. Therefore, A is the best choice because it encompasses the three primary groups of material properties.
