Thermal energy/
Experienced as heat; the energy of motion of all the particles in an object
Kinetic energy/
The energy of an object has because of its motion
Light energy/
Visible energy that is given off by some objects
Electrical energy/
The energy of moving electric charges
Potential energy/
Energy that is stored to be transformed at a later time
Chemical Energy/
Energy stored in chemical bonds
Sound energy/
Vibrating air that travels as waves to your ears
Radiation/
Energy that moves in the form of rays, waves or particles
Conduction/
The transfer of thermal energy by direct contact
Convection/
The transfer of thermal energy by the movement of a liquid such as water or air
What are the six types of energy that are involved in making pancakes.
Chemical, potential, lights, Kinetic, and electric.
What are the four states of matter?
Gas, solid, liquid, and plasma.
State the law of conservation of matter and energy:
The law of physics that states that energy cannot be created or destroyed; it can only change form.
What is specific heat?
It’s heat required to raise the temperature of 1g of a substance 1°C
What is the unit to measure energy?
Joules
Define and list an example of radiation:
Energy that moves in the form of rays, waves, or particles. After the bomb went off the radiation was terrible.
Define and list an example of convection:
The transfer of thermal energy by the movement of a fluid such as water. The hot sun warmed up the water so hot equals burnt myself when (I don’t know the rest I do not know)
Define and less an example of conduction:
The transfer of thermal energy by direct contact. I burnt my finger by touching the stove.
Characteristics and definition of a longitudinal wave:
Away that causes a medium to vibrate in a direction parallel to the direction in which the wave travels a slinky straight.
Characteristic and definition of a transverse wave:
A wave that causes a medium to vibrate in a direction perpendicular to the direction in which the wave travels a slinky when it is bent.
Frequency/
The number of creases or compressions and a wave that passes a point per unit in time, for sound waves, measured in hertz.
Crest/
The highest point of a transverse wave.
Trough/
The lowest point of a transverse wave.
Compression/
Region of a longitudinal wave where the particles of the medium have the highest density.
Refraction/
The change in direction of a wave when it enters a new medium with a different wave speed.
Wavelength/
The distance between successive crests or troughs and in transverse waves.
Reflection/
When the medium and energy in a wave is turned back from a hard surface.
Combustion/
Any types of burning usually a fuel ( with out idk)
Pollutants/
So harmful substance that is added to an environment
True or false
The temperature that measures where there is no thermal energy is 0°C
False
True or false
All endothermic reactions give off heat.
False
True or false
Sound is the transfer of thermal energy from one substance to another.
False
A reaction that requires heat for a chemical change is called_________.
Endothermic
We can convert from one form into another form (of energy) into another. That is called__________.
Transform
The energy involved in the handwarmers was __________ and _________.
Thermal energy and chemical energy
The lightbulb going on is a __________ that electric energy has been transferred. 2
Indicator and Inference
The measure of the average Connecticut energy of particles in a substance is the _________.
Temperature
The scale that contains absolute zero where there is no thermal energy is the _________ scale.
Kelvin
A temperature scale where water boils at 100°C and freezes at 0°C is the __________.
Celsius
The unit to measure energy when the work done is 100g moved 1m is called a __________.
Joule
The quantity whose value may change over the course of an experiment is the __________.
Variable
The variables that stayed the same experiment are called the ___________ variables or group.
Control
The variable that is manipulated or tested in an experiment is the ______________.
Independent variable.
