Term
What is a kinetic theory of matter states?
Definition
All matter is made of atoms and molecules that are always moving
Term
What is the world made of?
Definition
The world is made of matter which is solids,liquids,gasses and plasma
Term
What is a solid?
Definition
A solid holds its own shape,they have weight,solids take up space and are very tightly packed together
Term
What is a liquid?
Definition
Liquid is take the shape of their container,are loosely packed together, and have medium energy levels
Term
What is gas?
Definition
Gas is spread out the entire space given,they freely move, and have lots of energy
Term
What is plasma?
Definition
Plasma is lightning used in fluorescent light bulbs and neon lights,its a lot like gas but the bulbs are elecrically charged
Term
What does sound begin with?
Definition
sound begins with a vibration
Term
What does sound travel through?
Definition
Sound travels in waves through a medium
Term
What is a wave?
Definition
A wave is a form of energy
Term
What are mechanical waves?
Definition
Waves that do not need a medium to travel through
Term
What are sound waves measured in?
Definition
Frequency and amplitude
Term
Amplitude tells us.....
Definition
How loud the sound is
Term
What does conduction mean?
Definition
It's a transfer of heat through contact,it occurs in solids,transfers heat from something warmer to a less warm object
Term
What is convection?
Definition
It's heat's movement that occurs in liquids and gasses,transfer of heat through the movement of particles
Term
What is radiation?
Definition
It's the transfer of energy as waves, travel through matter or empty space
Term
What is kinetic energy?
Definition
Kinetic energy is a motion or a movement
Term
What is a electromagnetic wave?
Definition
Waves that do not need a medium to travel through
Term
What is convection?
Definition
Heat movement that occurs in liquids and gasses, transfer of heat through the movement of particles.
Term
What color does an opaque object reflect?
Definition
The wave lengths of the light of the object
Term
What does Reflection mean?
Definition
Reflection is the process by which light bounces off an object
Term
What is Refraction?
Definition
It's causing you to see something that isn't there
Term
What is Prism?
Definition
Something that light goes into
Term
What is Spectrum?
Definition
It's the range of wave lengths of electromagnetic waves.
Term
What is light?
Definition
A form of electromagnetic radiation
Term
What is heat?
Definition
Heat is a themal energy
Term
What is Conduction?
Definition
The heat moves from one object to another
Term
What is Convection?
Definition
Heat transferred by movement of currents within a fluid
Term
What is radiation?
Definition
Transfer of heat that doesn't need a matter to travel through
Term
What is an insulator?
Definition
A material that doesn't conduct heat well
Term
What is a Conductor?
Definition
Its a material that conducts heat well
Term
What is an angle of reflection?
Definition
It's a sound wave bouning off a solid
Term
What is pitch?
Definition
Pitch is a sound is a description of how high or low a sound seems to someone
Term
What is Reflection?
Definition
The process by which light bounces off an object
Term
What is vibration?
Definition
It's a sound wave as the energy travels through 2 mediums
Term
What is an Angle of Incidence?
Definition
It's when a sound wave comes in and bounces off a solid object
Term
What is a medium?
Definition
It's matter that sounds travels through
