Physical Science - Atoms, Energy, and Substances

Atoms

100

Substance that has mass and volume. 

What is matter?

200

One of the 3 subatomic particles inside atoms, located in orbitals and has a negative charge. 

What is an atom?

300

One of the 3 subatomic particles inside atoms, located in the nucleus.  It has a positive charge. 

What is a proton?

400

One of the 3 subatomic particles inside an atom, located in the nucleus.  It has no charge. 

What is a neutron?

500

Our current model of the atom.  It places the electrons in orbitals, rather than orbits and describes the shapes of all the orbitals.  

What is the quantum model?

Substances

100

Sweet tea is this type of mixture.  

Homogenous mixture

200

Gold can be classified as this type of substance.

An element

300

An elements identity is determined by its quantity of what?

Protons

400

This type of substance is formed by chemical reactions

Compounds

500

Any variety of the atoms of an element, differing in the cumber of neutrons the atoms have in their nuclei. 

Isotope

Energy

100

Energy in motion is called what?

Kinetic energy

200

The type of energy locked into the bonds of molecules.  

Chemical potential energy

300

A chain reaction that begins when a neutron shatters the nucleus of an uranium atom.  

Fission

400

Waves of pure energy at any wavelength in the electromagnetic spectrum

electromagnetic energy

500

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

Conservation of Energy

100

The law that states: Energy can be neither created nor destroyed, only changed in form. 

The law of conservation of energy

200

The type of heat transfer that occurs when energy moves by infrared electromagnetic waves. 

Radiation

300

The type of heat transfer that occurs when vibrating atoms in solids cause nearby atoms to vibrate too.

Conduction

400

The chemical potential energy in a firecracker transforms into what 3 types of energy?

Kinetic energy (flying debris), heat/light, acoustic energy

500

A force that converts the kinetic energy of motion into heat. (Hint: think of sliding down a slide)

Friction

Wild Card

100

What is the name of this class?

physical science

200

The lowest temperature theoretically possible; the temperature at which all molecular motion ceases.

absolute zero (0 Kelvin)

300

The measure of how much matter there is in a given substance

mass

400

The majority of elements on the periodic table are: metals, nonmetals, or metalloids?

Metals

500

Rainwater that has a pH below 7; caused by emissions of sulfur dioxide, nitrogen oxide, and other pollutants. 

acid rain
