What is the ideal gas constant
It is a universal constant used for all gases.
What is the best way to make a supersaturated solution
What does not describe the process the wright brothers used to create the first airplane
The wright brothers figured out how to outfit the plane with
wings that flapped, similar to birds' wings. - Apex- Chemistry
Semester 2.
Which of these describes something that happens as a pilot gets close to the speed of sound
More drag is created because the molecules cannot "hear" the
airplane coming.
Which of these does not describe the wright brothers first attempts at flight
They mimicked the flight of birds.
What substance will break rather than bend
Ice will break rather then bend
What is a challenge that the engineer of a high-altitude airplane would need to consider
The airplane may succumb to the power of gravity as lift
decreases at higher altitudes.
Which of these does not accurately describe the Wright brothers first airplane
it had wings that flapped similat to birds wings
As pilots get closer to the speed of sound
When pilots get closer to the speed of sound it gets harder for
the plane to fly. It could also depend on the how the pilot
flees.
Adding external protrusions to a wing such as fuel pods water tanks and missiles would be useful
In order to answer this you will have to give me more
information. You will have to give me a question to answer.
What forms of the ideal gas law would you use to calculate the number of moles of gas
Probable you think to the law of Avogadro.
A concentration unit expressed in units of moles of solute per kilogram of solvent
Supersonic flight can cause molecules on the surface of an airplane to break apart and chemically react what additional challenges to flight does this create
This causes alot of heat that the airplane must be shielded from
What is a phase diagram
a diagram showing the effects of temperature and pressure on
phase
Increasing an airplane's speed or wing size does which of the following
Generates more lifting force
Bikers wear spandex clothing to make themselves more aerodynamic. Which of the following forces does this clothing counteract
Mary is biking downhill. she notcies that her shirt and hair begin to pull back on her and blow in the wind that she is creating as she moves faster. This wind is an example of which of the following
All airplanes have mass therefore what force pulls them toward the ground
What does An airplane attempting to fly higher than 300000 ft do
Begin to succumb to the power of gravity because of the decrease in lift
The hot expanding gases generated by the combustion reactions in the engines are
released through the back of the engine to propel it and the airplane foward
In supersonic flights molecules break apart and react chemically. safety features protects the plane
Which of the following is an expression of Boyle's law
