Q

What are the four states of matter?

A

Gas, solid, liquid, and plasma.

22
Q

State the law of conservation of matter and energy:

A

The law of physics that states that energy cannot be created or destroyed; it can only change form.

23
Q

What is specific heat?

A

It’s heat required to raise the temperature of 1g of a substance 1°C

24
Q

What is the unit to measure energy?

A

Joules

25
Q

Define and list an example of radiation:

A

Energy that moves in the form of rays, waves, or particles. After the bomb went off the radiation was terrible.

26
Q

Define and list an example of convection:

A

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)

27
Q

Define and less an example of conduction:

A

The transfer of thermal energy by direct contact. I burnt my finger by touching the stove.

28
Q

Characteristics and definition of a longitudinal wave:

A

Away that causes a medium to vibrate in a direction parallel to the direction in which the wave travels a slinky straight.

29
Q

Characteristic and definition of a transverse wave:

A

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.

30
Q

Frequency/

A

The number of creases or compressions and a wave that passes a point per unit in time, for sound waves, measured in hertz.

31
Q

Crest/

A

The highest point of a transverse wave.

32
Q

Trough/

A

The lowest point of a transverse wave.

33
Q

Compression/

A

Region of a longitudinal wave where the particles of the medium have the highest density.

34
Q

Refraction/

A

The change in direction of a wave when it enters a new medium with a different wave speed.

35
Q

Wavelength/

A

The distance between successive crests or troughs and in transverse waves.

36
Q

Reflection/

A

When the medium and energy in a wave is turned back from a hard surface.

37
Q

Combustion/

A

Any types of burning usually a fuel ( with out idk)

38
Q

Pollutants/

A

So harmful substance that is added to an environment
