Properties Of Solids And Liquids Question 302

Question: With rise in temperature, density of a given body changes according to one of the following relations

Options:

A)ρ=ρ0[1+γdθ]

B)ρ=ρ0[1γdθ]

C)ρ=ρ0γdθ

D)ρ=ρ0/γdθ

Show Answer

Answer:

Correct Answer: B

Solution:

Since, with increase in temperature, volume of given body increases, while mass remains constant so that density will decrease. i.e. ρρ0=m/Vm/V0=V0V=V0V0(1+rΔθ)=(1γΔθ)

ρ=ρ0(1γΔθ)
