Matter
What are the three types of matter
Gas, solid ,liquid
What is separated solid ?
matter with a set volume and shape
What is a force?
a push or pull acting upon an object resulting from its interaction with another object
What is energy?( i dont know how any one could get this wrong)
what is needed to do work or cause change
what is a conductor?
a material that allows electricity (electric charge) or heat to pass through it easily.
Name the gasses
Nitrogen , oxygen , carbon Dioxide , helium
what is a mixture?
A combination of two or more substances that are not chemically bonded and can be separated physically.
If you are riding a bike and stop pedaling, what force causes you to slow down?
friction
True or False: Energy can be created or destroyed.
false
what is a insulator?
a material that resists or prevents the flow of energy
What is relative density?
how dense something is compared with a reference material
What is a solution?
A solution is a homogeneous mixture of two or more substances, typically featuring a smaller amount of a dissolved substance (solute) uniformly distributed within a larger amount of another substance (solvent
What force pulls objects toward the center of the Earth?
gravity
Kinetic energy is energy of-
motion
What does conductors do
allow energy to move
What is a measurement that could float on water?
Anything below 1 like 0.5
What is an example of a mixture?
Trail mix, salad, or sand and water.
What is the net force necessary to give a 3.0 kg mass, initially at rest, an acceleration of 5.0 m/s²?"
The net force necessary is 15.0 N.
What type of energy transfer occurs when you turn on a light bulb?
Electrical to Light/Heat)
Which of these materials is an insulator: aluminum foil, iron nail, copper penny, or glass marble?
glass marble
Why does matter dominate antimatter when symmetric creation laws should produce equal parts?
Matter dominates antimatter due to a tiny, early-universe imbalance—likely one extra matter particle for every billion matter-antimatter pairs—known as baryon asymmetry.
What is a heterogeneous mixture?
A mixture where you can clearly see the different parts, such as cereal in milk.
is a bowl of cereal a mixture?
yeah,( if u got this wrong, please open a book )
How does energy transfer occur between a hot sun and a cold Earth through a vacuum where no particles exist,
electromagnetic radiation,
What defines the boundary between a conductor and an insulator at the atomic level?
the mobility of valence electrons and the presence of a forbidden energy gap (band gap) between the valence and conduction bands.
