A cubical metal solid block is heated. How will its volume change ?

1.	A cubical metal solid block is heated. How will its volume change ?
Answer» When a solid is heated, it expands in all directions. The volume of a cube also increases. Let V₀ be the volume of cube of side L₀ at 0°C. i.e. V₀ = L₃₀ – V When temperature increases to t°C each side increases to V_t ∴ V_t = L_t³ Increase in volume = (V_t — V₀) [L_t³ — L₀³] Increase in temperature = (t — O)°C = t°C

Answer»

When a solid is heated, it expands in all directions. The volume of a cube also increases.

Let V₀ be the volume of cube of side L₀ at 0°C. i.e. V₀ = L₃₀ – V

When temperature increases to t°C each side increases to V_t

∴ V_t = L_t³

Increase in volume = (V_t — V₀) [L_t³ — L₀³]

Increase in temperature = (t — O)°C = t°C
