What is Easier to Hold ? Explain Why? Rock Water Helium from a balloon? We will complete a starter everyday as class begins. Get out a sheet of paper. Write Science Starter on the top. Today’s Date.

Science Starter Answer in complete sentences... You leave a towel out on a beach on a hot, sunny day. After a few hours, you return to get the towel. How has the temperature of the towel changed? Why did it change?

Science Starter What has a defined shape and defined volume? Solid Liquid and Gas are 3 States of ____________ How are the particles arranged in a crystal? How are the particles arranged in a amorphous solid?

States of matter Eq: what are the three states of matter

States of Matter Solid: definite volume and definite shape. Particles are fixed together and do not move Crystalline solid are in a specific structure. Amorphous solid have no regular pattern. Liquids: undefined shape a defined volume. Particles are free to move but remain in close contact. Viscosity determine how thick it is. Gas: undefined shape and undefined volume. Particles spread apart

Solid Solid: definite volume and definite shape. Particles are fixed together and do not move Crystalline solid are in a specific structure. Amorphous solid have no regular pattern.

Crystalline Structure Crystals such as Salt (NaCl) Sugar C 12 H 22 O 11, Snow (H 2 O) Molecules and Atoms are arranged in a regular pattern.

Regular Pattern

Amorphous Solid solid in which the atoms and molecules are not organized in a regular lattice pattern. Such solids include glass, plastic, and gel.

Liquid Liquids: undefined shape but defined volume. Particles are free to move but remain in close contact. Does not keep shape Takes the shape of the container it is in. Molecules are loosely packed. Viscosity determine how thick it is.

Viscosity Is the resistance of a liquid to flow. The higher the viscosity the stronger the attraction of the molecules in the liquid to each other.

Gas Gas: undefined shape and undefined volume. Particles spread apart Particles move freely separate from each other and only touch when they collide. Gas has no definite shape and no definite volume, it fills all available space.

Properties of gas Gas is a very special state of matter it is everywhere. The amount of space it takes up is its volume. Gas can undergo a change in volume easier than a solid or liquid.

How Matter Changes States

Changes in States of Matter In melting the particles in the solid vibrate so fast that they break free from their fixed position. In freezing the particles in the liquid move so slowly that they begin to take a fixed position. In vaporization (boiling) the particles in a liquid gain enough energy to move independently. In condensation the particles in a gas lose enough thermal energy to form a liquid. In sublimation particles of a solid do not pass through the liquid stage as they form a gas.
