Q

Conversation of energy

A

The law of conservation of energy states that energy cannot be created or destroyed but can only be changed from one form to another or transferred from one object to another.

Q

Radiation

A

Heat moving by waves. Can move through the vacuum of space

19
Q

what is a conductor

A

a material that can conduct heat

20
Q

True or false: an insulator traps heat

A

False

21
Q

If i were to go to the public pool and the part of me that wasn’t in the pool got hot what form of heat transfer is that

A

Radiation

22
Q

My teacher went to school in her car and the high was 115f and she left her car in the sun she touched the car and burned her elf what type of thermal energy transfer is this

A

conduction

23
Q

my mom went to a grocery store and she saw a big fan why is the father

A

the fan is there for the purpose of convection

24
Q

Definition of thermal energy transfer radiation

A

heat moving through light waves

25
Q

Definition of thermal energy transfer Conduction

A

when the heat moves through a solid

26
Q

Definition of thermal energy transfer convection

A

to have hot air go up or to move the air

27
Q

Convection

A

Heat moving by molecules going to different places

28
Q

Radiation

A

Heat traveling through heat waves and light

29
Q

What happens to particles as they heat up?

A

They spread out from each other, and occupy more space

30
Q

I want to know: How will be going to bed later affect how tired I am in the morning. What would be the control?

A

Me going to bed at the regular time and seeing how i feel to compare

31
Q

I want to know: How will be going to bed later affect how tired I am in the morning. What would be the independent variable.

A

The time I choose to go to bed at night

32
Q

I want to know: How will be going to bed later affect how tired I am in the morning. What wound be the dependent variable?

A

How tired I am in the morning

33
Q

I want to know: How will be going to bed later affect how tired I am in the morning. What are some constants for this experiment?

A

my bed, me, the time I wake up in the morning

34
Q

liquid

A

the state of matter that the molecules slide past each other

35
Q

solid

A

the state of matter that the molecules only have enough energy to vibrate

36
Q

gas

A

the state of matter that the molecules move super freely and don’t even touch like if they are social distancing

37
Q

insulator

A

a material that stops heat from traveling

38
Q

Keep studying you got this

A

keep studying you got this

39
Q

what state of matter has complete freedom

A)Solid

B) LIquid

C)Gas

D)Plasma

A

A)Incorrect
B)Incorrect
C)Correct
D)incorrect

40
Q

which state of mater dose not move much

A

solid

41
Q

which state of mater has the ability to slide passed each other

A

liquid

42
Q

Which state of matter only Vibrates

A)Solid

B) LIquid

C)Gas

D)Plasma

A

A)ICorrect
B)Incorrect
C)Incorrect
D)incorrect

43
Q

True or False

plasma a state of matter

A

False plasma is not a state of matter because they do not take up space and has no mass like lightning or fire if you object to fire being a plasma it is a plasma because what it is using as fuel must be a solid or oil

44

What state of matter has more freedom then a solid

A)Solid

B) LIquid

C)Gas

D)Plasma

A

A)incorrect
B)correct
C)correct
D)incorrect
