# Volume or Cubical Expansion

Volume or Cubical Expansion When a solid is heated and its volume increases, then the expansion is called volume expansion (or) cubical expansion. Consider a rectangular parallel piped of slides l₁, l₂ and l₃. Its initial volume (V₀) = l₁ x l₂ x l₃. Differentiating both sides with respect to T, we get: . dV/ Read more about Volume or Cubical Expansion[…]
