Measurement
the ability of a substance, the solute, to form a solution with another substance, the solvent.
What is solubility?
A substance dissolved in another substance.
What is a solute?
The number of protons found in the nucleus of an atom of an element.
What is atomic number?
Change in velocity / Change in time
What is acceleration?
Process that makes the Sun hot.
What is nuclear fusion?
The quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The SI unit is joule per kelvin per kilogram.
What is specific heat?
the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
What is pressure?
Protons + Neutrons = ?
What is atomic mass?
the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
What is voltage?
Heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
What is convection?
The property of matter that determines its resistance to acceleration.
What is mass?
The force on the object due to gravity.
What is weight?
The only group of elements on the Periodic Table with a full shell of valence electrons.
What are noble gases?
Any interaction that, when unopposed, will change the motion of an object.
What is a force?
The change in frequency of a wave (or other periodic event) for an observer moving relative to its source.
What is the Doppler Effect?
Measure of the average kinetic energy of the random microscopic motions of microscopic particles, such as electrons, atoms, and molecules, that move freely within the material.
What is temperature?
Protons - Electrons
What is charge?
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties.
What are isotopes?
a type of physical interaction that occurs between electrically charged particles.
What is electromagnetic force?
The bending of a wave when it enters a medium where its speed is different.
What is refraction?
An object, event, idea, feeling, time period, or any other type of category you are trying to measure.
What is a variable?
the hypothetical charge of an atom if all of its bonds to different atoms were fully ionic.
What is the oxidation number?
An atom in which the number of electrons and protons is not the same.
What is an ion?
Part of the electromagnetic spectrum with the lowest frequency.
What are radio waves?
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
What is radiation?
