Density Flashcards

All 4 cards in this deck

What is the equation for density, with units?

$\rho = m \div V$
density (kg/m³) = mass (kg) ÷ volume (m³)

In terms of particle spacing, why is steam less dense than liquid water?

The space between the particles in steam is bigger than in water, so there are fewer particles per unit volume.

How do you convert a density in g/cm³ into kg/m³?

Multiply by 1000 (1 g/cm³ = 1000 kg/m³).

In general, how do the densities of solids, liquids and gases compare?

Solids are usually the densest, liquids are less dense, and gases are the least dense.
