Solids, Liquids and Gases Chapter 3

What will I learn today? Today we will compare and contrast the states of matter using action words, Cornell notes, and a Venn Diagram.

1. States of Matter 2. Solid – What is it? 3. Anything that has a definite shape and definite volume 3. Particles of a solid 4. Closely locked in position 4. Vibrate 5. Move back and forth slowly

2. Types of solids 3. Crystalline solid 4. contain particles in regular, repeating patterns. 4. Examples 5. salt 5. Quartz

3. Amorphous Solids 4. Contain particles not arranged in a regular pattern. 4. Example 5. Butter 5. Plastic 5. Rubber

2. Liquid – what is it? 3. Contains a definite volume, but no shape 3. Particles are loosely connected 3. Particles move faster than a solid, but slower than a gas

2. Gas – what is it? 3. a fluid that can change volume 3. No definite shape 3. squeeze together in a container 3. Move in all directions 3. More energy 3. atoms and molecules are free to move independently, colliding frequently

Warm Up In your science journals answer the following questions: Would you rather be an amorphous solid or crystalline solid? Explain why. How would you determine if a liquid had high viscosity or low viscosity? What is the difference between the two?

Today we will analyze the states of matter using Cornell Notes, task cards, and vocab maps

1. States of matter 2. Liquids 3. A type of fluid – what is it? 4. a substance that flows. 3.Particles are about the same distance apart 3. A gas can also be a fluid

4. Surface tension – what is it? 3. Properties of liquids 4. Surface tension – what is it? 5. result of an inward pull among molecules of a liquid that brings the molecules on the surface closer together 5. Surface acts like a skin 5. Examples 6. bug walking on water http://www.planet-scicast.com/view_clip.cfm?cit_id=2845&tab=friend

4. Viscosity – what is it? 5. liquids resistance to flowing 5. depends on the size and shape 5. high viscosity = flow slowly 6. Honey 5. low viscosity = flow quickly 6. Water

HW Create a vocab map for each of the following terms 1. Fluid 2. Surface tension 3. Viscosity

Today we will Compare and contrast the changes of states of matter using cornell notes, task cards, and a vocab maps

1. Changes of States of matter 2. Changes between solids and liquids 3. To change from a solid to a liquid, thermal energy is increased. 3. Any change in thermal energy = a change in molecular motion!

3. Melting – what is it? 4. change in state from solid to a liquid 4. Melting point – what is it? 5. melting occurs at a specific temperature 5. melting point of water is 0oC 4. Particles vibrate rapidly and break apart as thermal energy is added

3. Freezing – what is it? 4. change from a liquid to a solid 4. Particles move so slowly that they begin to take on a fixed position due to losing thermal energy 3. Both freezing and melting are physical changes

2. Changes between a liquid and a gas 3. Vaporization – what is it? 4. Change from liquid to a gas 4. Occurs when particles in a liquid gain enough thermal energy to move independently

4. Two types 5.Evaporation – what is it? 6. only takes place on the surface 5. Boiling – what is it? 6. when a liquid changes to a gas below and at the surface 6. boiling point – what is it? 7. Temperature at which a liquid boils. 7. Depends on air pressure

3. Condensation – what is it? 4. change in state from a gas to a liquid 4. Gas particles lose thermal energy 4. Examples 5. Clouds 5. Breathing on a mirror

2. Changes between Solid and Gas 3. Sublimation – what is it? 4. Solids gain enough energy to change into a gas 4. Example 5. Snow not reaching the ground 3. Particles do not pass through a liquid state

HW NTG pages 51-53

Review Questions Write the correct answer on the white board

A liquid has a Constant temperature Definite shape Definite volume Crystal structure

The change from a gas to a liquid is called Evaporation Melting Condensation Sublimation

Which of the following is not a characteristic of a crystalline solid? Particles arranged in repeating patterns Becomes softer and softer as temperature rises Made of crystals Has a distinct melting point

Which of the following is not an example of vaporization? Water rising into dry air that moves over the ocean Bubbles forming as water boils Wet pavement drying after a rain shower Water droplets forming on a mirror

Because of surface tension, a liquid Resists flowing Forms a crystalline solid Takes the shape of its container Forms droplets

A liquid with a low viscosity Has a definite shape Flows quickly Flows slowly Fills its container

True or False During boiling, only particles on the surface of the liquid gain enough energy to become gas.

True or False The change from a solid to a liquid is condensation.

A kind of matter that keeps its shape and volume is a Solid Liquid Gas An alien

Particles of a gas Are packed very closely together Do not move Can spread far apart Have a definite volume

When particles of a gas lose thermal energy, they move Faster Slower At the same speed Immediately come to a halt

What will we learn today? Today we will describe the behavior of gases using notes, a chart and NTG.

1. Behavior of Gases 2. Measuring gases 3. need to know volume, temperature, pressure 3. Volume – what is it? 4. the amount of space that matter fills 3. Temperature – what is it? 4. measure of the average energy of motion of the particles of matter

3. Pressure – what is it? 4. force of its outward push divided by the area of the walls. 4. Pressure = Force Area 4. Measured in pascals

2. Temperature and volume 3. Charles's Law – what is it? 4. When temperature of a gas is increased at constant pressure, the volume increases 4. When the temperature of a gas is decreased at a constant pressure, its volume decreases.

Charles's Law

2. Pressure and Volume 3. Boyle’s Law – what is it? 4. When the pressure of a gas at constant temperature is increased, the volume of the gas decreases 4. when the pressure is decreased, the volume increases

Boyle’s Law

2. Pressure and Temperature 3. Increasing temperature increases pressure 3. When temperature decreases, the pressure decreases
