What is pressure

Pressure is the amount of force pressing on something. Air pressure is the force with which air presses. The force comes from the bombardment of the moving air particles.

A compelling or refracting influence ie. peer pressuere.

apex- the force of gas molecules hitting their container

Pressure is the continual physical force that is exerted against an object.
The amount of force acting per unit area is called pressure
What is the ideal gas constant

It is a universal constant used for all gases.

What is R in the ideal gas law equation

the ideal gas constant

D:

What is the best way to make a supersaturated solution

Heat the solution

What is the equation form of the ideal gas law

PV=nRT

D:

What does volatility refer to

the tendency of liquids to form a vapor

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.

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.

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

Drag

All airplanes have mass therefore what force pulls them toward the ground

gravity

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

What is stp apex

1 atm :)

What is the technique used to separate a solvent from a solution.

distillation (simple distillation)

If an engineer is designing a building in an area that has an occasional supersonic flight pass over it the engineer should apex

design extra reinforcements in the buildings windows so that they can withstand the vibrations from sonic booms

Which of the following is an expression of Boyle's law

PV = constant (apex)
