Transcript of States of Matter Project

States of Matter Solids Shape and Volume:
Both the shape and volume are definite. Particle Motion:
It stays stationary and compact unless it is dislodged. But the particles still vibrate. Comparison of particle movement in other states.
Liquid: Moves more freely than solids
Gas:Moves around more freely than solids or liquids Types of Solids
Crystalline:
When the particles in the
solid create a regular pattern.
Amorphous:
The particles are not arranged in a
regular pattern. Temperature on Solids:
Melting is caused by extreme heat and turns the solid into a liquid.
Freezing is when liquid gets very cold and turns into a solid. Absorption and release of Energy:
Solids absorb thermal energy so it melts and liquids lose thermal energy so they freeze. Changes of state:
Freezing: Liquid to Solid
Melting: Solid to Liquid
Sublimation: Solid to Gas Particle Energy:
Low Gases Shape and volume: Gas can change volume easily. If gas is trapped in a container the particles will separate or be squeezed together. Particle volume: When gas particles separate the particles move freely filling space. Accurately compare particle motion to that of other states: Unlike a solid, gas particles are able to move freely as they fill up space. Liquid particles can flow like gases particles but the liquid particles are still close together. Identify, define, and provide examples of gases: Gas is a substance neither solid or liquid such as air, oxygen, and carbon dioxide. Discuss impacts of temperature of gases: temperature is a measure of the average energy of a random motion of a particle. when the temperature goes up it hits the boiling point. When the temperature goes down it hits condensation. Tell what states are to be expected with absorption and release of energy: When a gas begins to boil it absorbs energy. Identify the correct term for the change of state: Condensation is the degrees of energy from gas to liquid. Vaporization is an increase of energy from liquid to gas. Deposition is when a gas changes into a solid without passing through a liquid state. Address particle energy: As a liquid boils it gains particle energy. By Missy, Adam, Jake Liquids Shape and Volume:
No shape, but definite volume Particle Motion:
Packed closely, but it can move freely,
allowing the liquid to flow Compare particle motion:
Solids: Vibrate back and forth
Gases: Spreads out or squeezes together Identify and give examples:
It is a state of matter that has a definite volume, but no shape
-Milk
-Water Impacts of temp.:
Freezing point
Boiling point Absorption and release of energy:
Melting- Solid to liquid
Freezing- Liquid to solid
Condensing- Gas to liquid Particle energy:
Medium The End!
