Q

If you continued to heat the water after it turned into a gas what do you think would happen to the temperature

A

I think the water would start boiling and then turn into a gas. It would continue to expand and the temperature will keep on increasing

Q

What is condensation

A

When the temperature of a gas becomes low enough, it changes from a solid to a liquid

17
Q

Vaporization

A

Memorization is the opposite of condensation… It is when something changes from a liquid to a gas

18
Q

Evaporation

A

Evaporation is vaporation that occurs on the surface of a liquid

19
Q

Boiling

A

Is evaporation that occurs in a liquid

20
Q

True or false Whether a liquid is changing to a gas or a gas is changing to a liquid a substance will always change phases at the same temperature

A

True

21
Q

True or false Whether a liquid is changing to a gas or a gas is changing to a liquid a substance will always change phases at a different temperature

A

False

22
Q

True or false once a substance reaches a certain point the particles cannot go any faster without changing to another state of matter

A

True

23
Q

True or false once a substance reaches a certain point the particles can go faster without changing to another state of matter

A

False

24
Q

What is potential energy

A

The stored energy due to the interactions due to particles or objects

25
Q

Are these examples of potential energy or not

Kinetic energy
Somethings can have both type of energy at the same time

A

No

26
Q

Are these examples of potential energy or not

Bow that’s pulled back
Top of a roller coaster
Food

A

Yes they are

27
Q

Does potential energy increase or decrease

A

Yes it increases

28
Q

As energy is transferred to a material temperature increase when the state of the material is NOT ___________

A

Charging

29
Q

As energy is transferred to a material temperature increase when the state of the material is NOT ___________

A

Charging

30
Q

The _________ energy of the particles increases and so does the ________ of particles

A

The kinetic energy of the particles increases and so does the speed of particles

31
Q

When a substance is changing state the temperature stays the same at the melting points.. The __________ energy of the particles increases and so does the _________ between the particles

A

When a substance is changing state the temperature stays the same at the melting points.. The potential energy of the particles increases and so does the distance between the particles

32
Q

CLAIM- A statement about the results of an investigation that describes the relationship between the independent and dependent variable

A

The amount of thermal energy determines the state of matter

33
Q

Specific data (quantitative and quantitative) that supports you claim

A

When I increased the thermal energy of ice it changed into water around 0*C

34
Q

Why are different substances at different states at the same temperature

A

Each substance has a unique melting and boiling point. The type of particles affect how much of energy is needed to cause a change in

35
Q

What does the total energy of a substance depend on

A

1 temperature
2 state of matter
3 mass of substance
4 type of matter of the substance

36
Q

Thermal energy is what

A

The total energy of a system
