  1. STATES OF MATTER

  2. STATES OF MATTER • The Four States of Matter • Four States • Solid • Liquid • Gas • Plasma

  3. STATES OF MATTER • Based upon particle arrangement • Based upon energy of particles • Based upon distance between particles

  4. Kinetic Theory of Matter Matter is made up of particles which are in continual random motion.

  5. STATES OF MATTERSOLIDS • Particles of solids are tightly packed, vibrating about a fixed position. • Solids have a definite shape and a definite volume. Heat

  6. STATES OF MATTERLIQUID • Particles of liquids are tightly packed, but are far enough apart to slide over one another. • Liquids have an indefinite shape and a definite volume. Heat

  7. STATES OF MATTERGAS • Particles of gases are very far apart and move freely. • Gases have an indefinite shape and an indefinite volume. Heat

  9. PHASE CHANGES

  10. Are clouds a solid, liquid, or gas? When you see steam, fog, or clouds, you are seeing water in a liquid state. • You are seeing small droplets of water in the condensed phase • Condensation is by definition the change of state from a gas to a liquid. • Water vapor itself is transparent. So clouds aren't water vapor, though they're obviously made primarily from condensed water vapor.

  11. What's the Difference Between Steam and Water Vapor?

  12. Steam • steam at 1 atmospheric pressure is defined to be water at a temperature of 100 degrees celsius or more. It is an invisible gas, and contains a large latent energy which is released when the steam condenses into droplets. It is highly dangerous, since its high energy content can scald very effectively per unit mass.

  13. Water Vapor • Water vapor is water in its gaseous state-instead of liquid or solid (ice). Water vapor is totally invisible. ... Water vapor is also the Earth's most important greenhouse gas, accounting for about 90% of the Earth's natural greenhouse effect, which helps keep the Earth warm enough to support life.

  14. Mist/Fog • Mist/Fog, on the other hand, is a harmless droplet state with only marginally more energy than bulk water. The extra energy is all due to the surface tension of the droplet formed, and is orders of magnitude smaller than the latent heat required to boil water. To make a mist or a fog, you can charge water electrically, and the electric repulsion will form droplets for you.

  15. Humidity • Humidity is water dissolved in air, and it is a different issue. Air will come to statistical equilibrium with liquid water when it has a certain water content, defined as 100% humidity. At any lower level, water will evaporate into the air, and at any higher level, water will spontaneously condense into droplets in the air.

  16. How does ice and water not fall to the ground • They do fall, but slowly enough that just a 1 or 2 MPH updraft is sufficient to keep a cloud aloft (thermal Brownian motion). They fall quite slowly, like the speed of a feather, and it's not hard to keep a feather in the air with a little wind below it.

  17. But what happens if you raise the temperature to super-high levels…between 1000°C and 1,000,000,000°C ? Will everything just be a gas?

  18. STATES OF MATTERPLASMA • A plasma is an ionized gas. • A plasma is a very good conductor of electricity and is affected by magnetic fields. • Plasmas, like gases have an indefinite shape and an indefinite volume. • Plasma is the common state of matter

  19. STATES OF MATTER LIQUID PLASMA SOLID GAS Tightly packed, in a regular pattern Vibrate, but do not move from place to place Close together with no regular arrangement. Vibrate, move about, and slide past each other Well separated with no regular arrangement. Vibrate and move freely at high speeds Has no definite volume or shape and is composed of electrical charged particles

  20. Some places where plasmas are found… 1.Flames

  21. 2. Lightning

  22. 3. Aurora (Northern Lights)

  23. The Sun is an example of a star in its plasma state
