Praxis 5511 Practice Test Practice Question
Which THREE of the following are properties of most metals in the solid state?
Correct Answer: A,B,C
Rationale: Metals in the solid state exhibit several key properties.
A: Malleable - Metals can be hammered or pressed into shapes without breaking, making malleability a defining characteristic.
B: Can conduct heat - Metals are excellent conductors of heat due to the free movement of electrons, allowing energy to transfer efficiently.
C: Can conduct electricity - Similar to heat, metals conduct electricity well because of their free-moving electrons.
D: Melt at 100°C - This is incorrect; most metals have melting points significantly higher than 100°C, with many exceeding 1000°C. Thus, options A, B, and C accurately describe properties of metals.
