Matter Basics
These are the three main particles that make up atoms.
What are protons, neutrons, and electrons?
This state of matter has a definite shape and definite volume.
What is a solid?
This is the layer of gases surrounding Earth.
What is the atmosphere?
This measures the average kinetic energy of atoms or molecules.
What is temperature?
This is a repeating back-and-forth motion.
What is oscillation?
Sound is this type of wave because it needs a medium.
What is a mechanical wave?
This atomic particle has a positive charge.
What is a proton?
This state of matter has a definite volume but takes the shape of its container.
What is a liquid?
This force helps cause atmospheric pressure by pulling air particles toward Earth.
What is gravity?
This is the transfer of thermal energy because of a temperature difference.
What is heat?
This is the highest point of a wave.
What is a crest?
This wave property mostly determines pitch.
What is frequency?
This atomic particle has a negative charge.
What is an electron?
This quantity is force divided by area.
What is pressure?
This gas law relates pressure and volume.
What is Boyle’s law?
This property tells how much heat is needed to raise a material’s temperature.
What is specific heat?
This measures the distance from one crest to the next crest.
What is wavelength?
A sound with higher frequency has this kind of pitch.
What is higher pitch?
This atomic particle has no charge.
What is a neutron?
This happens to liquid pressure as depth increases.
What is it increases?
What is Boyle’s law?
What is pressure increases?
A substance that heats up quickly has this kind of specific heat.
What is low specific heat?
This measures the height or size of a wave from the middle line.
What is amplitude?
This happens to the pitch of a sound when the source moves toward you.
What is the pitch increases?
This property is found by dividing mass by volume.
What is density?
This force is equal to the weight of the displaced fluid.
What is buoyant force?
This principle says faster-moving fluid has lower pressure.
What is Bernoulli’s principle?
This type of heat transfer does not require a medium.
What is radiation?
In this type of wave, particles move parallel to the direction the wave travels.
What is a longitudinal wave?
This happens when something vibrates at its natural frequency.
What is resonance?
In general, this state of matter has the greatest density.
What is a solid?
This principle says pressure in a confined fluid is transmitted equally everywhere.
What is Pascal’s principle?
This fourth state of matter is found in stars, lightning, neon signs, and plasma TVs.
What is plasma?
This usually happens to most materials when they are heated.
What is they expand?
These two measurements are needed to calculate wave speed.
What are wavelength and frequency?
Beat frequency is found by taking the difference between these.
What are two frequencies?
