Answer:
1. anything that has mass and occupies space
2. it is made up of atoms and molecules
4. solid molecules are closely packed and liquid molecules are loosely packed
5. solid liquid and gas
Answer:
1. In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.
2. At the most fundamental level, matter is composed of elementary particles known as quarks and leptons (the class of elementary particles that includes electrons). Quarks combine into protons and neutrons and, along with electrons, form atoms of the elements of the periodic table, such as hydrogen, oxygen, and iron.
3. All matter is made up of very small particles.
There is space between particles.
All particles in a pure substance are the same.
The particles in matter are always in motion.
Particles are attracted to each other.
4. Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.
5. solid; liquid and gas.
6. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles. ... Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
