Q

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

A

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

16
Q

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

A

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

17
Q

Can gas because press why or why not

A

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

18
Q

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

A

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

19
Q

Compression

A

We do send a volume as a result of applied force

20
Q

Contraction

A

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

21
Q

Expansion

A

A increase the volume

22
Q

Kinetic energy

A

Energy of motion

23
Q

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

A

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

24
Q

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

A

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

25
Q

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

A

The particle would hit More often harder faster and spread out

26
Q

Can solid liquid and gas on expand and contract explain

A

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

27
Q

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

A

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

28
Q

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

A

It can’t because both object has equilibrium

29
Q

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

A

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

30
Q

Define Calorie energy transfer equilibrium heat and temperature

A

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

31
Q

Condensation

A

Phrase change of gas to liquid

32
Q

Dissolve

A

Cause by liquid

33
Q

Chemical interaction

A

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

34
Q

Evaporation

A

To change phrase from liquid to solid

35
Q

Melting

A

Solid to liquid

36
Q

What is the difference between melting and dissolving

A

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

37
Q

Every

A

Even
