Energy
What unit is energy measured in?
Joules (J)
Everything is made up of tiny particles. True or False
True
What is temperature a measure of?
Kinetic energy
What is sound?
Sound is a form of energy made by vibrations
How fast does light travel?
300,000,000 m/s
What is Energy?
The ability to make things happen or cause changes
What happens to the kinetic energy when the temperature increases?
The kinetic energy increases as temperature rises
What unit is heat measured in?
Joules (J)
What is it called when the air particles from a sound are bunched together?
Compressions
An object that releases or emits light is called what?
Luminous
What is energy transformation?
What state of matter has the particles packed close together and keeps their shape.
Solid state of matter
Energy that moves into materials to make them hotter and is the total energy of all particles within a substance
What states of matter can sound pass through?
Solids, liquids and gases
Why might we see an object that is not luminous?
Light is reflecting off it
What is energy transfer?
The movement of energy in the same form, from one object to another object.
This state of matter is where particles are packed closely together and are free to move or flow to take the shape of their container
Liquid state of matter
What unit do we measure heat in?
Where can't sound travel through and why?
Space (vacuum) because there are no air particles.
There are two types of reflections, what are they?
Regular and Diffusion
What is the law of conservation of energy?
The law of conservation of energy states that energy cannot be created or destroyed. It can only be changed from one type to another
Describe gas particles in a state of matter
Particles not bound together, able to freely move in straight lines until they collide, fills their space
If a bathtub was 40 degrees Celsius and a teacup was 60 degrees Celsius, which one has a higher temperature and which one has more heat?
The teacup has a hotter temperature, and the bathtub contains more heat.
There are two types of sound waves, what are they?
Transverse and Longitudinal
What is the ray that is going in and the ray that is going out of a reflection called?
Incident Ray and Reflected ray
