PRESENTATION OUTLINE

1.

solid

  • A solid has a definite shape and a definite volume.
  • The particles that are in a solid are very packed a very close together and are tightly fixed in one position.

2.

liquid

  • A liquid has a definite volume but no shape of its own without a container it becomes a wide shallow puddle.
  • Liquid does have a constant volume.

3.

gas

  • Like liquid a gas is a fluid unlike liquid however, a gas can change volume very easily .
  • A gases particles will and can spread apart very quickly

freezing

  • The change of liquid to a solid is called freezing its the reverse of melting
  • The time it does that is because they move so slow that they form regular patterns.

5.

Melting

  • The change from a solid to a liquid is called melting in most substances melting occurs a a certain point called the melting point

6.

condensation

  • Its the opposite of vaporization its called condensation one example when you breath into the mirror the air particle form into tiny water droplets.

7.

evaporation

  • A shrinking puddle is the example the puddle gains energy from the puddle and the particle on the top of the puddle rise into the air and escape.

12.

homogeneous

  • in the backround there are many of the same thing that look the the same if you drop another in the same color and size shape you can not easily find something like that in there

13.

heterogeneous

  • and in the backround of this picture you see many dots that are not the same color say you drop a brown dot you will easily be able to find it in there

physical changes

  • Some physical changes are choping down trees and puting dye in water

15.

chemical changes

  • some chemical changes are fire works and how they explode and how you set fire to wooden logs for fires

16.

mass

  • mass is an object of measurement the amount of matter in an object depends can determian how much mass there is

17.

volume

  • solid and liquids take up space gases have volume too example a balloon

18.

potential energy

  • is an example like a drawn bow or that you are storing energy

19.

kinetic energy

  • is an fact that can do work on anything it hits

20.

law of conversation and mass

  • states that for any system closed to all tranfers to matter and energy
