Study Notes
Physical State of Matter
- Solids: fixed shape, fixed volume, cannot be compressed, strong force of attraction between particles, high melting and boiling point, least inter-particle space, ordered arrangement of particles, particles are not free to move, do not flow, exert pressure on walls of container.
- Liquids: no fixed shape, fixed volume, cannot be compressed, less force of attraction between particles, low melting and boiling point, more inter-particle space, little order in arrangement of particles, particles can move, flow, and exert pressure on walls of container.
- Gases: no fixed shape, no fixed volume, can be compressed, least force of attraction between particles, low melting and boiling point, maximum inter-particle space, no order in arrangement of particles, particles move freely, flow, and exert pressure on walls of container.
Plasma
- Fourth state of matter
- Consists of super-energetic and super-excited particles in the form of ionized gases
- Fluorescent tubes and neon signs contain plasma
- Plasma glows with a special color depending on the nature of the gas
- Stars and sun glow due to the presence of plasma in them
Bose-Einstein Condensate (BEC)
- Fifth state of matter
- Formed when matter is cooled to near absolute zero (-273°C)
- Particles have very low energy, overlapping each other to form a single super atom
- A rotating BEC can be used as a model for a black hole
- Can be used to "freeze" pulses of light and release them again when the condensate breaks down
Characteristics of Matter
- Matter is composed of minutely small particles called atoms
- Particles of matter have space between them
- Particles of matter are continuously moving and possess kinetic energy
- Particles of matter attract each other
Diffusion and Evaporation
- Diffusion is the process of particles moving from an area of higher concentration to an area of lower concentration
- Evaporation is the process of particles changing from a liquid state to a gas state
- Both diffusion and evaporation increase with an increase in temperature
- Liquids with higher density diffuse slower than liquids with lower density
- The rate of diffusion increases with an increase in temperature
