A substance whose particle is made of two or more different kind of Atom

Question 3

Mixture

Answer 3

Two or more substances together

Question 4

Substance

Answer 4

A type of matter defined by unique particle

Question 5

What evidence can you observed that proves the chemical reaction has taken place

Answer 5

Evidence equals fizzy bubbles color sound temperature change phrase or form light

Question 6

Explain how the modern. Parodic table of elements is organized and displayed

Answer 6

The periodic table is organized and displayed by left to right and of mass.

Question 7

A student just arrived to our school and has not studied the periodic table. How are you explain to the student had the table is organized

Answer 7

USA to the student that the periodic table is organized by left to right and of mass

Question 8

Who is the father of the periodic table

Answer 8

Dmitry ivanovick Mendeleyve

Question 9

Compress

Answer 9

Reduced in volume as a result of applied pressure

Question 10

Expand

Answer 10

And increase the volume

Question 11

Gas

Answer 11

A phase of matter that has no definite shape or volume no ponds move freely freely can track compress expand

Question 12

Liquid

Answer 12

Loose bonds move all around each other contract and expand

Question 13

Solid solid

Answer 13

Contract right bonds

vibrate back-and-forth

Question 14

Particle

Answer 14

The smallest piece of a substance that is still a substance

Question 15

Sean investigated how it behaves in a close Syringe compressed air pushing the plunge it in as far as he could and then let go what happens to the pleasure plunger not pleasure

Answer 15

It can’t be compress and the particles pushed back up the plunger goes back where it was

Question 16

Sean investigated how air behaves in a close syringe he compressed air by pushing the plunger in as far as he could like go explain why the air did not remain compress

Answer 16

That is not me make compress because it was a closest him the air cannot get out

Question 17

Can gas because press why or why not

Answer 17

Yes gas can be compressed because there is space and air between The gas

Question 18

Tif the syringe contained 100 particles, how many will there be after Sean pushes the syringe’s plunger down I’m like oh

Answer 18

There will still be 100 particles because the syringe is the close system and particles and air can’t get out

Question 19

Compression

Answer 19

We do send a volume as a result of applied force

Question 20

Contraction

Answer 20

The reduction of volume of a sample of matter as a result of cooling

Question 21

Expansion

Answer 21

A increase the volume

Question 22

Kinetic energy

Answer 22

Energy of motion

Question 23

Describe how it particles move one trap in a balloon at room temperature

Answer 23

The air particles will still move about freely and at a rapid pace

Question 24

What would happen to the air particle in the balloon if they were cooled

Answer 24

The particle would move slower less often and they would also hit with less force and come closer together

Question 25

Explain what happened to air inside a close water bottle when it is heated

Answer 25

The particle would hit More often harder faster and spread out

Question 26

Can solid liquid and gas on expand and contract explain

Answer 26

Yes because they would have an increase/decrease in kinetic energy heat

Question 27

Explain what a liquid can contract and it can't be compress like a gas

Answer 27

Because liquid has bonds and is touching and gas particles has space between them

Question 28

Explain your energy transfers from one object that has the same temperature

Answer 28

It can't because both object has equilibrium

Question 29

Explain how energy transfers different temperature and also explain which direction does energy flow

Answer 29

The energy always flows from hot to cold. The direction energy flows is from hot to cold or high to low

Question 30

Define Calorie energy transfer equilibrium heat and temperature

Answer 30

Calorie = The unit of energy that will rise 1 g of water 1 Celsius Energy transferred = the movement of energy from one location to another Equilibrium = the condition in which a system experimenting no net change Heat = the form of energy related to KE Temperature = the average kinetic energy of particles in a substance

Question 31

Condensation

Answer 31

Phrase change of gas to liquid

Question 32

Dissolve

Answer 32

Cause by liquid

Question 33

Chemical interaction

Answer 33

A process during which start substance change into a new substance with different arrangements of Atom

Question 34

Evaporation

Answer 34

To change phrase from liquid to solid

Question 35

Melting

Answer 35

Solid to liquid

Question 36

What is the difference between melting and dissolving

Answer 36

When you melts it increased cheat and dissolveing is caused by liquid

Question 37

Every

Answer 37

Even
