Atoms
Substance that has mass and volume.
What is matter?
Sweet tea is this type of mixture.
Homogenous mixture
Energy in motion is called what?
Kinetic energy
The law that states: Energy can be neither created nor destroyed, only changed in form.
The law of conservation of energy
What is the name of this class?
physical science
One of the 3 subatomic particles inside atoms, located in orbitals and has a negative charge.
What is an atom?
Gold can be classified as this type of substance.
An element
The type of energy locked into the bonds of molecules.
Chemical potential energy
The type of heat transfer that occurs when energy moves by infrared electromagnetic waves.
The lowest temperature theoretically possible; the temperature at which all molecular motion ceases.
absolute zero (0 Kelvin)
One of the 3 subatomic particles inside atoms, located in the nucleus. It has a positive charge.
What is a proton?
An elements identity is determined by its quantity of what?
Protons
A chain reaction that begins when a neutron shatters the nucleus of an uranium atom.
Fission
The type of heat transfer that occurs when vibrating atoms in solids cause nearby atoms to vibrate too.
Conduction
The measure of how much matter there is in a given substance
mass
One of the 3 subatomic particles inside an atom, located in the nucleus. It has no charge.
What is a neutron?
This type of substance is formed by chemical reactions
Compounds
Waves of pure energy at any wavelength in the electromagnetic spectrum
electromagnetic energy
The chemical potential energy in a firecracker transforms into what 3 types of energy?
Kinetic energy (flying debris), heat/light, acoustic energy
Metals
What is the quantum model?
Any variety of the atoms of an element, differing in the cumber of neutrons the atoms have in their nuclei.
Isotope
This holds everything together and enables every process to happen. One of the basic constituents of the universe, the others being matter and intelligence.
Energy
A force that converts the kinetic energy of motion into heat. (Hint: think of sliding down a slide)
Friction
Rainwater that has a pH below 7; caused by emissions of sulfur dioxide, nitrogen oxide, and other pollutants.
acid rain
