Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.
Density describes how closely packed the particles are in a solid, liquid or gas. in a solid ‐ particles are tightly packed in a regular structure in a liquid ‐ particles are tightly packed but free ...
