Jeopardy
This method of heat transfer involves collisions of
molecules.
What is CONDUCTION
The only method that can transfer heat energy through the
vacuum of space.
What is RADIATION
This method can transfer heat energy in fluids (liquids and gases)?
What is CONVECTION?
This method of heat transfer involves density differences
What is CONVECTION?
What is CONDUCTION?
This method can transfer heat energy through solids.
This is the UNIT of measure for heat energy.
What is the Joule?
This substance has the highest specific heat of any common material.
What is WATER?
Of air, granite, and copper, this substance has the smallest
specific heat.
What is COPPER?
DAILY DAILY DOUBLEDOUBLE
Heat flows from a source to THIS.
What is a SINK?
If equal amounts of heat energy are added to equal masses of water, basalt, iron, and lead,
this substance will experience the smallest temperature
increase.
What is WATER?
3.98oC
At what temperature does water reach maximum
density?
4.18 joules/gram x Co
What is the specific heat of liquid water?
To melt 1g of ice at 0oC, this much energy must be added.
What are 334 J/g?
The greatest number of joules are released into the air when
H2O changes between this phase and this phase.
What is between water vapor and liquid water?
What must be happening if heat energy is added to water but the temperature doesn’t
change.
What is a change of phase?
What is ‘temperature’ actually measuring?
The average kinetic energy of the atoms or molecules
of a substance
At what temperature, in degrees Kelvin, does all molecular motion stop?
MUST GIVE NUMBER!
0 degrees Kelvin
The Kelvin equivalent of 140 degrees Fahrenheit.
What is 333 degrees K
Which of the following is the lowest temperature?
0oF, -10oC, 260oK
0oF
The number of degrees between the boiling point and freezing point of water on the
Kelvin scale?
100 degrees
Between which 2 consecutive points is the most energy
added?
D and E
By what process does heat energy
flow from A to B?
Conduction
At which letter location does
the air have the greatest density?
Location E
What process is illustrated
by the diagram?
Refraction
334 joules/g will be released
into the environment when going
from this letter to this letter.
From C to B
FINAL JEOPARDY
?
Impossible Heat Question
What will be the temperature of the water when
the system reaches
equilibrium?
50 degrees C
