thermodynamics basic Flashcards
which state of mater moves the moves freely
gas
What are molecules?
Everything that takes up room it made up of molecules
What is temperature
the amount of heat
Conversation of energy
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.
Increase
to add more things
Decrease
to remove things
Experimental group
The group that is changed
Control group
The group that is not changed
Kinetic energy
study of movement
Dependant variable
The variable that is measured
Independant variable
The variable that is changed
constant
stays the same
experimental group
something changes
control group
nothing changes
Which state of matter is tea
liquid
what is conduction
Heat traveling directly to something else
Convection
Heat moving by fluids. Hot molecules move around ex - air currents
Radiation
Heat moving by waves. Can move through the vacuum of space
what is a conductor
a material that can conduct heat
True or false: an insulator traps heat
False
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
Radiation
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
conduction
my mom went to a grocery store and she saw a big fan why is the father
the fan is there for the purpose of convection
Definition of thermal energy transfer radiation
heat moving through light waves
Definition of thermal energy transfer Conduction
when the heat moves through a solid
Definition of thermal energy transfer convection
to have hot air go up or to move the air
Convection
Heat moving by molecules going to different places
Radiation
Heat traveling through heat waves and light
What happens to particles as they heat up?
They spread out from each other, and occupy more space
I want to know: How will be going to bed later affect how tired I am in the morning. What would be the control?
Me going to bed at the regular time and seeing how i feel to compare
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.
The time I choose to go to bed at night
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?
How tired I am in the morning
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?
my bed, me, the time I wake up in the morning
liquid
the state of matter that the molecules slide past each other
solid
the state of matter that the molecules only have enough energy to vibrate
gas
the state of matter that the molecules move super freely and don’t even touch like if they are social distancing
insulator
a material that stops heat from traveling
Keep studying you got this
keep studying you got this
what state of matter has complete freedom
A)Solid
B) LIquid
C)Gas
D)Plasma
A)Incorrect
B)Incorrect
C)Correct
D)incorrect
which state of mater dose not move much
solid
which state of mater has the ability to slide passed each other
liquid
Which state of matter only Vibrates
A)Solid
B) LIquid
C)Gas
D)Plasma
A)ICorrect
B)Incorrect
C)Incorrect
D)incorrect
True or False
plasma a state of matter
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
What state of matter has more freedom then a solid
A)Solid
B) LIquid
C)Gas
D)Plasma
A)incorrect
B)correct
C)correct
D)incorrect
