Question

A cubical metal solid block is heated. Which is the type of expansion in this case?​

Answer 1

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 Vt ∴ Vt = Lt3 Increase in volume = (Vt — V0) [Lt3 — L03] Increase in temperature = (t — O)°C = t°C.

Don't know sorry dear . so sorry
