# Would the density of a hot liquid be greater or less than a cold liquid?

Would not the $\text{density}$ of the former solution BE GREATER than the latter solution?
$\rho ,$ $\text{density}$ $=$ $\text{Mass of substance"/"Volume of solution}$ and for chemists typically $\rho$ has units $g \cdot m {L}^{-} 1$ or $g \cdot c {m}^{-} 3$.
In general (for condensed phases) $\rho$ DECREASES (marginally) with increasing temperature in that $\text{volume}$ marginally increases while $\text{mass}$ is a constant. In any case the colder solvent contains more solute particles by the problem's specification, and should thus be intrinsically denser.
And thus ${\rho}_{\text{cold water solution">rho_"hot water solution}}$.
