Science 1
This is what makes a solid more dense than air.
What is the molecules are closer together?
This is what happens to molecules when they lose thermal energy.
What is slow down/get closer?
This is an object that has molecules.
What is everything with mass?
This is what molecules do when heated up.
What is move faster/spread out?
This is the direction energy transfers.
What is hot to cold?
This is the least dense object on Earth.
What is air?
This is the reason that black shirts get hotter.
What is they absorb more light?
This is an example of conduction.
What is any 2 objects touching?
This is why a big ice sculpture has more thermal energy than a little match.
What is more molecules to hold more energy?
This is why solids conduct heat better than gases.
What is particles closer together/more dense?
This is the best way to make things less dense.
What is: spread out molecules or heat them up?
This is the best insulator.
What is air?
This is an example of convection current.
What is boiling water?
This is the type of energy transfer that occurred when the metal spoon gets warm on a hot plate.
What is conduction?
This is the type of energy transfer that only happens when two items touch each other.
What is Conduction?
This is what makes a good conductor.
What is molecules close together?
This is why "Hot air rises".
What is molecules speed up and spread out to become less dense when heated?
This is what is happening when something feels cold to the touch.
What is energy is transferring from us to the object?
This is an example of radiation.
What is sun/fire?
This is the type of energy transfer that fire/the sun has.
What is Radiation?
This is the only type of energy transfer that can get through a vacuum.
What is radiation?
This is what makes a good insulator.
What is molecules spread out?
This is what thermal energy is.
What is total amount of thermal energy?
This is the pattern that a convection current makes.
What is up, put, down, in?
This is the type of energy transfer that happens in liquid or gas.
What is Convection?
