Are Class I materials generally larger or heavier than Class II materials?

Class I materials are typically associated with higher levels of electrical and mechanical protection, often leading to a larger or heavier design when compared to Class II materials, which are generally designed for less demanding applications. However, this does not mean that all Class I materials must be larger or heavier than Class II materials in every case. Certain factors, such as the specific application, the manufacturer's specifications, and the materials used can influence the size and weight of these classes.

Answering "False" indicates an understanding that while Class I materials can often be larger or heavier, there are exceptions based on the situation or design choices, meaning that it is not a strict rule. Hence, the statement is nuanced and context-dependent, allowing for variability in the physical characteristics of the materials in question.
