9
The first thermometer was developed by this
person.
10
Who is Galileo?
11
This temperature scale is used throughout the
world as a standard temperature unit of measure
for SCIENTIFIC MEASUREMETS
12
What is Kelvin?
13
Absolute Zero is what equivalent temperature in
Celsius?
14
What is -273.15oC?
15
The standard unit of measurement for thermal
energy is this.
16
What is a Joule?
17
All thermometers have these three things.
18
What is a sensor, a signal and a responder?
19
Name two points of the particle model of matter.
20
What is All matter is made of particles There
are tiny spaces between particles The particles
are always moving Increase in thermal energy
causes particles to move faster?
21
Explain, using the particle model, how a solid
can expand
22
What is, the particles of a solid move farther
apart increasing the volume (NOT mass) of an
object
23
Use the particle model to explain why there are
teeth on bridges.
24
Teeth allow for expansion and contraction. When
the bridge is cold, the particles get closer
together causing the teeth to separate.
25
Use the particle model to explain how a solid
like ice can turn into a liquid like water.
26
What is, when thermal energy is applied to the
ice, the particles begin to move faster and get
further apart causing the ice to melt and slowly
begin to become a liquid?
27
Look at the chart below and answer At what
temperature does oxygen freeze?
Substance Melting Point (oC) Boiling point (oC)
Oxygen -218 -183
28
What is -218oC?
29
Energy from the sun is _________________ when you
are wearing a black shirt.
30
What is absorbed?
31
A person getting warmed by a camp fire is what
type of heat transfer?
32
What is Radiation?
33
A house with active solar heating uses what type
of heat transfer?
34
What is convection?
35
A pot on a stove gets hot through what type of
heat transfer? (metal element to metal pot)
36
What is conduction?
37
A spoon getting hot in a bowl of soup is an
example of what type of heat transfer?

38
What is conduction?
39
Calculate the RSI value of 3cm of
newsprint Note 1 cm of newsprint has an RSI
value of 0.28
40
What is 0.84?
41
Styrofoam is a poor _________ but a good _________
42
What is conductor and insulator?
43
True or False Aluminum has a higher conductivity
than copper.
Material Conductivity
Aluminum 8 600
Copper 16 000
44
What is false?
45
Name two insulators off of the following chart
Material Conductivity
Air 1.0
Brass 4 600
Cork 1.8
Iron 2 000
46
What is air and cork?
47
Define Conductor.
48
What is the process of heat transfer from one
substance (an area of high thermal energy) to
another (an area of low thermal energy)
49
Heat from the earth is this type of energy.


50
What is geothermal energy?
51
Places like the Hoover Dam use this type of
energy.
52
What is a hydroelectric?
53
Energy stored in food is this type of energy.
54
What is chemical energy?
55
This type of energy uses both passive and active
forms.
56
What is solar energy?
57
Using one energy source for two purposes is
called this.
58
What is cogeneration?
59
Having large windows on the south side of you
home and small windows on the north side of your
home is an examples of what type of solar energy?
60
What is passive solar heat?
61
The type of wave that warms the Earth from the
sun is called this.
62
What is infrared waves?
63
What is the difference between heat and
temperature?
64
What is heat involves both mass and speed whereas
temperature involves just speed ?
65
What are the THREE states of matter?
66
What is solid, liquid and gas?
67
Look at the following chart and explain what the
freezing point of gold is.
Substance Melting point (oC) Boiling point (oC)
Gold 1064 2856
68
What is 1064 C?
