Ideal Gas Law and Kinetic Theory

Answer:
The ideal gas law states that
#PV=nRT# .Explanation:
The ideal gas law gives the relationship between a substance's mass, volume, its current temperature, the amount of moles of the substance, and the pressure it is currently in, by a simple equation.
In my words, I would say that it says that:
The product of the pressure and volume of a substance is directly proportional to the product of number of moles and the temperature of the substance.
For the symbols:
#P# is the pressure (usually measured in#"kPa"# )#V# is the volume (usually measured in#"L"# )#n# is the amount of moles#R# is the ideal gas constant (usually use#R=8.314* \ "L" \ "kPa" \ "mol"^-1 \ "K"^-1# )#T# is the temperature (usually measured in#"K"# )Note that no ideal gases are found to exist, but we can still use this equation for real-life gases, as they behave like ideal gas at low pressure and temperatures. But remember that, in real life, no gas will perfectly obey the ideal gas law.
