thermodynamics basic Flashcards
What’s the experimental group?
It’s the part of the experiment where the variables are being changed.
What is the control group?
A part of an experiment that doesn’t change. Use to compare your results to.
What is an Independent Variable
The variable that is controlled (not the control). The variable you choose to change.
What is a Control?
The one you use to compare the changes made by the experimental group.
What is Conduction?
The movement of heat through an object.
What’s Temperature?
It’s the average kinetic energy.
Does cold technically exist?
Cold does not exist but lack of heat does.
What is radiation?
Its heat that transfers through waves.
I want to know: How will be going to bed later affect how tired I am in the morning. What is the control in this experiment?
Me going to bed at my regular time and seeing 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 is the independent variable?
The time I choose to 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, what time I get up in the morning.
What is Convection?
The transfer of heat when it moves up due to it being less dense than the air around.
What is Conduction?
The transfer of heat through touch.
What is an Insulator?
Maintains state or prevents change of kinetic energy.
What is an Conductor?
Moves heat around or speeds up change of kinetic energy.
You are playing among us and you saw a vent. Is a vent a example of Radiation, Convection, or Conduction?
Convection
What is a liquid?
A liquid can slide past each other but does not have full freedom of movement.
Why are the molecules of gas further apart than other states of matter?
Because they have more kinetic energy to move faster and further apart
Jeff is cooking bacon. He touches the pan and it burns him. What kind of heat transfer is this?
Conduction.
As heat is added to molecules they…
speed up and move further apart
you are sitting in the sun and you are getting hot what type of heat transfer is this?
radiation
You are at the beach and you sadly get a sunburn. Are sun rays an example of Convection, Conduction, or Radiation?
Radiation.
It is the summer and you’re on your trampoline and the sun is very hot. Is the heat from the sun Radiation, Convection, or Conduction?
Radiation
Greg is sitting near a campfire. The campfire is warming him up, even though Greg is not touching it. What kind of heat transfer is this?
Radiation.
you are sitting in the sun and you are getting hot what type of heat transfer is this?
radiation
Conduction is when heat is transferred by heat waves: true or false
False: conduction is the transfer of heat through objects
An insulator is when the area maintains the heat, or keeps it out’ True or false
True!
You are in among us and you are making some Hot Coco. You see some steam rising from your cup. Does steam come from adding heat or adding cold/making it cooler?
Adding Heat.
Mark is playing in the snow. He is wearing gloves so that his hands don’t get cold. Are the the gloves and example of a conductor, or an insulator?
Insulator.
You are in among us and your buddy is trying to do a task but they don’t know what kinetic energy is!!!!!!! Define Kinetic energy.
The speed of molecules in a certain solid, gas, or liquid.
There is a reactor meltdown and your buddy is trying to measure the temp of something but they don’t know what a thermometer is! Explain what a thermometer is to your old pal.
The tool that is used to measure the average kinetic energy of a state of matter.
You are freaking out in among us and a sus person walks up to you and says “Thermal Energy is the Energy of Cold.” Is this True or False?
FALSE!!! The sus guy is really an imposter and (if you said true) he kills you and runs away. YOU LOSE!!!! (If you said False then Crewmates win!!)
