States of Matter – Response to Text

Answer each question to the best of your ability, using full sentences and make sure to include detail in your responses.

 

1.   What are the three states of matter commonly found on Earth, and what are TWO of their properties?

 

State #1:Solid	State #2:Liquid	State #3:Gas
Property #1:Solids are hard substances like butter, wood or brick.	Property #1 Liquids are substances that have a definite volume but take the shape of their container.	Property #1 Gases are substances that do not have a definite shape or volume.
Property #2:Solids can be formed by using other states like butter can be formed just by shaking cream inside a jar.	Property #2 Liquids have a specific boiling point, which is the temperature at which they change from a liquid to a gas.	Property #2 Gases can be compressed and expanded easily, and they do not have a specific boiling or melting point.

 

2. What is the fourth state of matter called?

1. Electrons
2. Particles
3. Plasma
4. Laser

 

3. What happens to the speed of molecules when the temperature increases?

1. They move quicker
2. They move slower
3. They move at the same speed
4. They explode.

 

4. Explain what happens to the molecules in a liquid when they are cooled down to their freezing point.

 

The average energy of the molecules decreases.

 

5. Explain what happens to the molecules in a liquid when they are heated to their boiling point.

 

More energetic molecules change to a gas,spread out,and form bubbles.These rise to the surface and enter the atmosphere.

 

6. What could be the reason for the fact that gases can be compressed more easily than solids or liquids?

 

Gases are compressible because most volume of a gas is composed of the large amounts of empty space between the gas particles.

 

7. Explain how each of these jobs might need to und4b verstand and work with different types of matter. (You may need to research to find out more)

 

Job	Gas	Liquid	Solid
Baker	Gas is the steam that will be formed from baking.	Liquid will be used while baking milk will be used such as water.	The solid will be created from whatever they baked.
Fire Fighter	This is formed from the fire when there is a bizarre fire.	This is uses to take out the fire which is water form their hose which is attached to their truck	They use metal which is a ladder they use to get into high places that are hard to get into from the inside.
Welder	These include shielding the arc from impurities like air, dust, and other gases;	Welding Fluid is a special coolant for welding equipment equipped with liquid cooling.	Applies heat to metal pieces,melting and fusing them.
