Guida verificata passo dopo passo1
Recall the four common states of matter: solid, liquid, gas, and plasma.
Understand that the packing of atoms or molecules depends on the intermolecular forces and the amount of kinetic energy they have.
In solids, particles are arranged in a fixed, closely packed structure with very little movement, leading to the highest density and tightest packing.
In liquids, particles are close but can move past each other, so they are less tightly packed than in solids.
In gases and plasma, particles have much more kinetic energy and are far apart, resulting in the least dense and least tightly packed state.
