100
This is the flow of electric charge.
What is electric current?
100
This is a region of space that surrounds a magnet and exerts a force on magnets and objects made of magnetic materials.
What is a magnetic field?
100
This gas law states that mass can neither be created nor destroyed, only rearranged.
What is the law of conservation of mass?
100
This gas is necessary for every combustion reaction.
What is oxygen?
100
This is the SI base unit of mass.
What is the kilogram?
200
This type of current, found in household electric outlets, changes direction many times each second.
What is alternating current?
200
These are the regions of a magnet that exert the strongest force.
What are magnetic poles?
200
This law states that charge can be transferred from object to object, but it cannot be created or destroyed.
What is the law of conservation of charge?
200
These two gases are produced by the combustion of any hydrocarbon or carbohydrate.
What are carbon dioxide and water?
200
This is the Si unit of voltage?
What is the volt (v)?
300
This type of electric current, like that produced by batteries, does not change direction of flow.
What is direct current?
300
These are groups of atoms with aligned magnetic poles.
What are magnetic domains?
300
This gas law states that the volume of a gas is inversely proportional to the pressure applied to it.
What is Boyle's law?
300
If a gas has a volume of 2.0 L at 1.5 atm, this will be its volume at 0.75 atm assuming a constant temperature.
What is 4.0L?
300
This is the SI base unit of power.
What is the watt (w)?
400
This is a closed path that electric current follows.
What is electric circuit?
400
This is a wire wrapped into a coil which produces a magnetic field while current is flowing through it.
What is a solenoid?
400
This gas law states that the volume of a gas is inversely proportional to the pressure applied to it.
What is Boyle's law?
400
If a gas sample has a volume of 3.0 L at -23°C, this will be its volume at 27°C assuming a constant pressure.
What is 3.6L?
400
This is the SI base unit of electric resistance.
What is the ohm (Ω)?
500
This is the SI base unit of electric current?
What is the ampere(amp)?
500
This is the generation of an electric current by a changing magnetic field.
What is electromagnetic induction?
500
This gas law states that the volume of a gas is directly proportional to its temperature.
What is Charles's Law?
500
Gasoline is primarily composed of this eight- carbon hydrocarbon.
What is octane?
500
This SI unit is used to count very large numbers of items.
What is the mole (mol)?
