Flashcards
Solid
Solid
A state of matter with a definite shape and volume, due to particles held together by forces and arranged in specific positions.
Crystalline Solid
Crystalline Solid
A solid with an ordered arrangement of particles, resulting in varied properties depending on the direction of the particles.
Amorphous Solid
Amorphous Solid
A solid with a disordered arrangement of particles, resulting in isotropic properties and lacking a specific melting point.
