thermodynamics basic Flashcards
What is Kinetic Energy?
The Energy of Movement or Motion
Investigation
looking deeper to find out if its right or wrong or why it did what it did
Predict
make a theory on what you think will happen
Control Group
the thing you do not change. A frame of reference that’s usually the “normal” or a group that doesn’t have
Volume
How much space something takes up
Conservation of Energy
“Energy cannot be created or destroyed”
Solid
A state of matter that is made of a structure with close atoms and a set volume and shape. Solids vibrate instead of moving
Control Group
The group that you don’t change. A reference
Independent Variable
The Variable you change
Dependent Variable
A variable that is changed by another variable
Experiment Group
The group that you change
Solid
A state of matter is a structure with a set volume and shape. Solids vibrate instead of moving
What is Diffusion?
The movement of energy from high to low density
Liquid
A state of matter that is less dense and has a set volume but has an undefined shape
Gas
A state of matter that is spread out and has an undefined volume and shape
Force of attraction
A force that holds molecules together. It gets weaker the hotter or faster the molecules are
I want to know: How will be going to bed later affect how tired I am in the morning. What is the control in the experiment?
Going to bed at the regular time and seeing how tired I am as a comparison.
I want to know: How will be going to bed later affect how tired I am in the morning. What is the independent variable?
The time i go to bed
I want to know: How will be going to bed later affect how tired I am in the morning. What is 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 in this experiment?
My bed, me, the time I wake up in the morning
Does cold exist?
No, it doesn’t
If I sit at a fireplace, what type of transfer is that?
Radiation
If I touch a pot’s handle, what type of transfer is that?
Conduction
If I hold my hands over a fire, what type of transfer is that?
Convection
An insulator is
Something that keeps heat in by being bad at transferring energy
A conductor is
Something that loses heat by being great at transferring energy
Does heat move from cold to hot or hot to cold?
Hot to Cold
What are the three types of heat transfer
Radiation, Conduction, and Convection
if you get sunburned which have you experienced:
1) Radiation
2) Convection
3) Conduction
1)Radiation
If you feel the heat coming through of something what is it:
1) Radiation
2) Convection
3) Conduction
3)Conduction
What is conduction?
Conduction is when you touch something that is touching a hot thing, and then you get burned or feel the heat.
If you can feel the heat on top of a stove the heat transfer is radiation.
true or false?
False the heat transfer is convection.
If you burn your self with a metal fire poker is the heat transfer:
1) conduction
2) radiation
3) convection
1)conduction
What has faster molecules
A. Gas
B. Solid
C. Water
A.Gas
