Question

By increasing the temperature of a liquid its (A) volume and density decreases (B) volume and density increases (C) volume increases and density decreases (D) volume decreases and density increases

Tardigrade Admin · Accepted Answer

When we heat the liquid volume increases.
Let the initial volume be V.
If temperature is increase then the new volume

V_{1} = V + V α Δ T

So

V_{1} > V

< b r / > ρ = \frac{m}{V} < b r / >

Since mass remains the same, so increase in volume will decrease the density.

< b r / > ρ_{1} = \frac{m}{V _{1}} < b r / >

< b r / > ρ_{1} < ρ < b r / >

Q. By increasing the temperature of a liquid its

volume and density decreases

volume and density increases

volume increases and density decreases

volume decreases and density increases

When we heat the liquid volume increases. Let the initial volume be V. If temperature is increase then the new volume V1​=V+VαΔT So V1​>V <br/>ρ=Vm​<br/> Since mass remains the same, so increase in volume will decrease the density. <br/>ρ1​=V1​m​<br/> <br/>ρ1​<ρ<br/>
