Wood blocks- solid
Fluorescent light bulb- plasma
Steam and helium filled balloon is gas
Water from a faucet and swimming pool is liquid
- Can be distinguished at the molecular level by how the particles are held together
- The phase of matter is considered a physical property because a change in a substance’s phase does not change the chemical properties or identity of the substance.
- The phases of matter are determined by the kinetic energy of the particles and the attractive forces between the particles.
- Attractions between particles, called intermolecular forces.
- The effects of the motion of the particles on these attractions determines the arrangement of the particles in a sample of matter.
- Electrically charged gas because of extreme temperatures, the particles move so quickly that their collisions release electrons from the atoms.
- Mixture of electrons and positively charged ions with high kinetic energy is described as the plasma phrase.
- Because of its extreme temperature, plasma is not common on earth.
- The sun and stars are mad of elements in the plasma state, and plasmas can also be found inside of a glowing fluorescent light bulb, small fluorescent lights in plasma television screens, and at locations where high- energy lightning strikes in the air.
The particles in solids are packed tightly together. In most solids, the particles are arranged in a specific, fixed pattern.
Particles cannot move around very much; they mainly vibrate in place. Particles cannot move around very much, they have a fixed volume and shape. They do not take the shapes or sizes of their containers.
The particles in liquids are fairly close together, but not as close together as those in solids. They are not arranged in a fixed pattern.
The particles in liquids have
