In what direction does metal expand when heated with no restraint?

Horizontally
Vertically
Diagonally
Volumetrically (all directions)

The correct answer is: Volumetrically (all directions)

Heat causes molecules to move and fluctuate with more energy, increasing the distance between them and causing an expansion in all directions. Options A, B, and C all refer to specific directions of expansion, but in reality, metal will expand in all directions when heated with no restraint.
