ICE cars
What does ICE stand for
Internal Combustion Engine
What is typically the coldest part of the day and why??
Right around sunrise because the sun has been not heating for the longest
What is it called when something burns
Combustion
What is electicity
The movement of electrons
What is density
The amount of "stuff" in a certain area (or volume)
Roughly speaking, how efficient are ICE cars
About 20-30% efficient
How much snowfall does Antarctica receive? Describe why it receives this amount.
Only a few inches. It is too cold for EVAPORATION to occur and too cold for the DENSE air to hold moisture.
Even though Hydrogen is the lightest element, why do we use helium in birthday balloons?
BOOM, BOOM! BYEBYE!
What do we do with coal before we combust it??
Pulverize it
Why do hot air balloons launch in the morning
Because the air is at its coldest and cold air sinks, making it easier for hot air to rise
Where does most of the energy go in ICE engines
To heat
What are typically the top 2 snowiest months in the Front Range (Fort Collins, Denver, Monument, Colorado Springs)
The 3rd and 4th months of the year
What is the name for the coldest possible temperature and what happens to atoms at that temperature
Absolute zero. Atoms stop moving (or almost completely stop)
Why do we pulverize coal
To increase the SURFACE area and make it more efficient to burn
How does dew form
Air cools overnight and becomes more dense. As it becomes more dense the water molecules in the air condense, making water. When the air warms in the morning, it becomes less dense, expands, rises and leaves the water behind.
What is the name of the "finger-sized" part of an ICE engine that ignites the fuel
Spark plug
Where do hurricanes typically form
In the Atlantic near the equator
Why do we put perishable foods in the fridge or freezer
Cold slows molecular movement which means germs/bacteria/mold don't grow as quickly
After we combust coal or natural gas what is the next step in the process of making electricity
Boiling water to create steam
Why is there water on the outside of Dad's drink at Applebee's and how did the water get there?
Cold glass cools the air around it causing air to become more dense and the water molecules condense
Describe the process for an ICE engine
1- Intake
2- Compression
3-Ignite/Combustion
4-Exhause
How do hurricanes form
Warm waters along the equator evaporate and the warm air is very active. Due to the spinning of Earth and the coriolis effect, the warm, energetic, moist air begins to rotate.
What was DDT used for and why was it banned.
It was an insecticide for crops and it was banned because it harmed the eggs of bald eagles leading to a drop in births, causing bald eagles to go on the endangered species list!
What does steam do in an electrical plant?
Steam turns a turbine (which rotates copper around a magnet)
What are the 2 variables in density
The amount of area/volume
The amount of things/stuff
