Vocabulary Puzzle

objective
Objective
  • Explain and provide examples of methods of heat energy transfer
  • Illustrate and describe the kinetic theory of matter, including phase changes.
  • Demonstrate an understanding of the relationship between kinetic and potential energies.
  • The Main 3 Components to Electricity

STUDENT VERNACULAR

  • Using vocabulary explain how heat moves from place to place, matter to matter
  • Using vocabulary explain how Kinetic Energy is responsible for the various states of matter (Solid, Liquid, Gas, etc)
  • How does an objects Energy level change as it moves from Potential Energy (PE) to Kinetic Energy (KE)

All 5 Phases
  • Solid, Liquid, Gas, Plasma, BoseEinstein
  • All Based upon the Amount of KE
states of matter
States of Matter

There are Three Main States of Matter:

  • Solid
  • Liquid
  • Gas
  • However there are many states currently.
states of matter1
States of Matter

Solid

  • Particles arranged in definite order
  • Vibrate
  • Close together

Liquid

  • Particles arranged in Random order
  • Slide past, attaching and releasing
  • Close together

Gas

  • Particles not arranged.
  • Scattered, Random
  • Fast
  • Very Spread out

Other States:

  • Plasma-Lightening
    • Excited/Ionized Gases
other states of matter
Other States of Matter
  • Ordinary Temps
    • Liquid Crystal States (Digital Watch) Mlcls pnt sm direc
    • Amorphous Solid (Glass, Rubber, Polystyrene)
    • Magnetically-ordered States (moments aligned 2 dif ways)
  • Low Temps
    • Superconductors (Cold Magnets –MRI)
    • Superfluids (Climbing helium 3 or 6)
    • Bose-Einstein Condensates (called “Fifth State” helium 4)
  • High Energy
    • Plasma (ionized gas lightning, stars, sun)
    • Quark-gluon Plasma (CERN 2000 Observe individual Quarks)
  • Proposed States
    • Degenerate Matter (White dwarves and Neutron Stars)
    • Supersolid (Solid with superfluid properties
    • String-net liquid (atoms have the same spin, not normal)
    • Rydberg Matter (condensation of excited atoms)

energy terms2
Energy Terms
  • Temperature- Average kinetic energy KE of the individual particle
thermal energy1
Thermal Energy
  • Total amount of Kinetic Energy from Particles. As Kinetic Energy of particles increases, so does the Thermal energy.(Heat Energy) The particles move faster.
energy transfer
Energy Transfer

Heat-

Movement of Thermal energy from a substance at a higher temperature to another at a lower temperature

energy transfer1
Energy Transfer

Conduction-

Transfer of Thermal Energy, without particles moving. Transfer by touching, Direct Contact

transfer of energy
Transfer of Energy

Convection-

The transfer of energy by movement of Fluids. Earths mantle as well as water in a pot on the stove.

energy transfer2
Energy Transfer

Radiation-

Transfer of energy by or through EM Waves (Electromagnetic). Sun’s rays, hot lamps, tanning salon.
