Question

write a formula for the variation of density of a solid with temperature is given by the formula?

Answer 1

from expansion of solids we know that 
v = v₀(1+γt)                             .....1
here v = final volume 
       v₀ = initial volume
       γ = co-efficient of volume expansion
       t = tempareture difference
as the mass(m) remains same during expansion so we can write from equation 1
m/v = m/{v₀(1+γt)}
⇒m/v = m/v₀ × 1/(1+γt)
⇒ρ = ρ₀ × (1+γt)⁻¹ (ρ = density)
⇒ρ = ρ₀(1-γt)

Answer 2

Answer:

Solids: All forms of matter expand on heating; but in solids, heating has very little effect on the volume of the solid. Solids do not expand significantly to bring any considerable change in their volumes. As a result, the density of a solid does not change much with temperature variation.
