Wood blocks- solid
Hammer- solid
Lightning- plasma
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.
PLASMA
- 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.
SOLIDS
-Particle Arrangement:
The particles in solids are packed tightly together. In most solids, the particles are arranged in a specific, fixed pattern.
Particle Motion:
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.
LIQUIDS
-Particle Arrangement:
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.
Particle Motion:
The particles in liquids have
