Matter
This defines the identity of an atom.
What is the number of protons?
These are the two main categories of energy.
What is potential and kinetic energy?
These are the two subcatorgories that fall under fluids.
What are liquids and gases?
This is the unit used to measure the strength of a force.
What is a Newton (N)?
This is what the number of neutrons in an atom is called.
What is the Mass #?
This is the purest form of matter.
What are elements?
This energy is a form of potential energy that is stored in chemical bonds between atoms.
What is chemical energy?
This is the formula for pressure.
What is force/area?
This is the overall force on an object.
What is the net force?
Who is Dmitri Mendeleev?
These are two things that matter must have.
What are mass and volume?
This energy is energy made from the movement of water, usually by dams or rivers.
What is hydropower?
This is the force that opposes or restricts motion.
What is drag?
These are the three different ways an object can accelerate.
What are speeding up, slowing down, and changing direction?
These are the least reactive elements on the periodic table.
What are Noble Gases/Group 18?
These are chemical bonds that are formed when electrons are transferred from one atom to another.
What are ionic bonds?
These are the 5 main types of nonrenewable energy resources.
What are petroleum, natural gas, coal, propane, and fossil fuels?
This is why bubbles are round.
What is the equal outward pressure exerted in all directions inside bubbles?
This law is dependent on the mass and acceleration of an object.
What is Newton's 2nd Law?
This is why hydrogen is placed with the metals in group 1 on the periodic table.
What is hydrogen's 1 valence electron?
These are strong chemical links that occur when two atoms share one or more pairs of electrons.
What are covalent bonds?
This is the percentage of coal capacity to generate electricity in the U.S.
What is 52%?
This is the reason as to why humans are not crushed by atmospheric pressure.
What is the equal outward pressure exerted by fluids inside the human body?
This is what a Newton is equal to in terms of mass and acceleration.
What is M/S?
Rusting iron and rotting food are chemical changes because they form new substances, while this process of a solid turning directly into a gas without melting is purely physical.
What is sublimation?
