BTr

Matter is made up of particles, when there is more particles in a little space the object is more dense.

Matter exists is in the form of a solid, liquid, or gas.

According to ACS, solids, liquids, and gases are made of very small particles called atoms and molecules. The University of Colorado (PHET) provides a simulator that allows its viewers to visualize what happens when heat is added or subtracted to the elements of neon, argon, oxygen, and water in their three states. It's especially helpful to see elements made of atoms that cannot be broken down any further.

What are three states of matter?

Three states of matter are solid, liquid, and gas.

According to Livescience.com, plasma (a super-heated gas) as well as human-made states like "Bose-Einstein condensates." CK-12 provides a simulator that allows its viewers to visualize a solid, liquid, and gas at the molecular level being poured into a container.
