Ideal Gas Flashcards
(13 cards)
What is an ideal gas?
a theoretical gas that perfectly follows the ideal gas law, where interactions between gas molecules are negligible.
True or False: Ideal gases can condense into liquids under high pressure and low temperature.
False
Fill in the blank: The ideal gas law is expressed as PV = ____.
nRT
What does the ‘R’ represent in the ideal gas law?
The ideal gas constant.
Which of the following conditions is most likely to make real gases behave like ideal gases? A) High pressure B) Low temperature C) High temperature D) Low volume
C) High temperature
What are the units of pressure in the ideal gas law?
Atmospheres (atm), Pascals (Pa), or millimeters of mercury (mmHg).
True or False: The volume of an ideal gas is directly proportional to its temperature when pressure is held constant.
True
What is Avogadro’s law?
states that the ideal gas volume is proportional to the # moles as long as temp/pressure stay constant
In the ideal gas law, what does ‘n’ represent?
The number of moles of the gas.
What is the significance of the ideal gas law in scientific calculations?
It allows for the calculation of the state of a gas based on its pressure, volume, temperature, and amount of substance.
which law states that pressure and volume are inversely related at constant temp?
Boyle’s law
True or false: Charles’ law states that pressure is directly proportional to temp at constant volume
false
Gay-Lussac’s law
which law states that volume and temp are directly proportional at constant pressure?
Charles’ law
