The ideal gas law was first stated by French engineer and physist Emile Clapeyron in 1834 as a combination of Boyles Law and Charles Law. I deal gases include no point mass, no forces of attract,perfect elastic collision and straight line motion. The Ideal gas law is a combination of Boyles law (which relates volume and pressure) Charles law (which relates volume and temperature). and avogadro's law (which relates volume and moles). These all combine to create the Ideal gas law.
PV=nRT
P= pressure of gas
V= volume it occupies
n= # of molecules
R= Ideal gas constant (0.0821) L atm/mol K
T= temperature (K absolute units)
The ideal gas relates the pressure, temperature and volume of an ideal gas. It is an equation used for hypothetical ideal gases. The ideal gas law is used to make approximations of the behavior of different gases under many conditions(taken into account this law has limitations).
The ideal gas law was used later on to determine the pressure, temperature and volume of an ideal gas. For example,
A 12.0 g sample of gas occupies 19.2 L at STP. What is the molecular weight of this gas?
PV = nRT:
(1.00 atm) (19.2 L) = (n) (0.08206) (273 K)n = 0.8570518 mol
Determine the molecular weight:
12.0 g / 0.8570518 mol = 14.0 g/mol3) Since it is at STP, we can also use molar volume:
(19.2 L / 12.0 g) = (22.414 L / x )19.2x = 268.968
x = 14.0 g/mol
you can only use molar volume when you are at STP.
The ideal gas law can be found in many different day to day things such as in engineering to determine the capacity of storage containers. It is also helpful in determining the efficiency and standard operation of equipment.
