What is the ideal gas constant

It is a universal constant used for all gases.

Why are aircraft fuel tanks designed to be located in the wing

To utilize the wing space for the fuel,

What is R in the ideal gas law equation

the ideal gas constant

D:

What does the ideal gas law describe

Charles' Law and other observations of gases are incorporated into the Ideal Gas Law. The Ideal Gas Law states that in an ideal gas the relationship between pressure, volume, temperature, and mass as PV = nRT, where P is pressure, V is volume, n is the number of moles (a measure of mass), R is the gas constant, and T is temperature. While this law specifically applies to ideal gases, most gases approximate the Ideal Gas Law under most conditions. Of particular note is the inclusion of density (mass and volume) and temperature, indicating a relationship between these three properties.


The relationship between the pressure, volume, temperature, and amount of a gas ~APEX

What is the total pressure of a gas mixture containing partial pressures of 0.23 ATM 0.42 ATM and 0.89 ATM

1.54 atm

What is the pressure of 4 moles of helium in a 50 L tank at 308 K

2.02 atm

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.

is slippery a property of bases

Yes. It is a property of base.

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.

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

This is called molality.

What best summarizes the ideal gas law apex

PV=nRT

Increasing an airplane's speed or wing size does which of the following

Generates more lifting force

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

gravity

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

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

What is a homogeneous mixture equivalent to

A homogeneous mixture has only one phase.

What will result from increasing the temperature of gas

Increasing the temperature of gas the volume increase.

which of the following is an example of an Arrhenius acid

HI
