Ideal gas Law:
The ideal gas law describes the behavior of an ideal gas, but can also be used when applied to real gases under a wide variety of conditions. This allows us to use this law to predict the behavior of the gas when the gas is subjected to changes in pressure, volume or temperature.
The Ideal Gas Law is expressed as
PV = nRT
where
P = Pressure
V = Volume
n = number of moles of gas particles
T = Absolute Temperature in Kelvin
and
R is the Gas Constant.
The Gas Constant, R, while a constant, depends on the units used to measure pressure and volume. Here are a few values of R depending on the units.
R = 0.0821 liter·atm/mol·K
R = 8.3145 J/mol·K
R = 8.2057 m3·atm/mol·K
R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K
Note: In our calculation block we use unit of pressure as atms , volume as liters and temperature as Kelvin.
Hence R = 0.0821 liter·atm/mol·K is taken as constant. please conver the values to these units before entering them in calculation block.
