5005 Praxis Practice Test Practice Question
Which of the following is a measure of the ease with which heat can pass through a material?
Correct Answer: B
Rationale: Heat conductivity refers to a material's ability to transfer heat energy, making it the appropriate measure in this context.
Option A, malleability, describes a material's ability to be deformed under stress, particularly in shaping processes, and does not pertain to heat transfer.
Option C, permeability, relates to the ability of a material to allow fluids or gases to pass through it, which is unrelated to thermal properties.
Option D, elasticity, measures a material's ability to return to its original shape after deformation, again not relevant to heat transfer.
