Approximate Degrees
Boiling point of water
What is 100 degrees C?
Heat transfer process in solids
What is conduction?
This is what transfers heat through radiation
What are electromagnetic waves?
I need to heat 100g of water and 100g of gold 1 degree C. Which one will take less energy to heat?
What is gold?
The sum of all of the kinetic energies possessed by a substance
20 degrees C is about what in Fahrenheit?
What is 72 degrees F
This type of oven cooks food fast by moving heated air.
What is a convection oven?
This is the primary radiation that transfers heat
What is infrared radiation (IR)?
The high water capacity of this substance moderates the weather and temperature of Earth.
What is water?
This is the term for the temperature at which there is no internal energy; atoms are literally standing still.
What is absolute zero (0 Kelvin)?
62 degrees F in Celsius
What is 15 degrees C?
Heat transfer process in fluids
What is convection?
An object that is giving off a large amount of IR is what?
What is hot?
Which is better, a coffee cup insulated with a vacuum or with styrofoam?
What is a vacuum?
Within a sealed container, the collisions between particles (molecules and atoms) and the container walls.
What is pressure?
-273.2 degrees C in K
What is 0 K
This is why a metal spoon handle left in hot soup becomes hot throughout, even though only the bottom is touching the liquid.
What is conduction?
This is the ONLY method of heat transfer that can work through the vacuum of space.
What is radiation?
Assuming equal mass and thickness, between a copper kettle and an aluminum pot, this one will heat up faster on a stove.
What is a copper kettle?
Rank these four materials from LOWEST to HIGHEST specific heat capacity: water, aluminum, wood, and gold.
What is gold, aluminum, wood, water?
273.2 K in F
What is 32 degrees F
This explains why smoke from a campfire rises, even though air and smoke have similar densities at the same temperature.
What is convection?
Why do desert areas experience extreme temperature swings between day and night, while humid coastal areas have more moderate temperature ranges.
What is: Dry air allows radiation to escape to space freely at night (rapid cooling), while water vapor in humid air absorbs and re-emits IR radiation back to Earth, slowing heat loss and moderating temperature?
For keeping a home insulated, which is better: a single pane of glass 20mm thick, or two 10mm panes with an air gap in between?
What is two 10mm panes with air gap?
As a car drives down the road, friction between the tire and road causes the tire to heat up. What also is happening to the tire?
What is air pressure increasing and tire is swelling?
