Question

The ratio of fraction change in volume △V to temperature change △T of body is called​

Answer 1

Answer:

ANSWER

Let the density of liquid at 0∘C be ρ0.

⟹ρt1∘C=1+γt1ρ0

Also ρt2∘C=1+γt2ρ0

The buoyant force at the both temperatures would be same and equal to the weight of the solid.

⟹f1Vρt1∘Cg=f2Vρt2∘Cg

⟹1+γt1f1=1+γt2f2

⟹γ=f1t1−f2t2f1−f
