Ideal gases are a hypothetical gas composed of molecules that follow a few rules:
- Ideal Gas do not attract or repel each other
- Ideal gas themselves take up no volume.
The pressure (P), volume (V) and temperature (T) of an ideal gas is related by a simple formula called the ideal gas law. The relationship is given by the equation:
PV = nRT
Where P is the pressure of the gas, V is the volume taken up by the gas, T is the temperature of the gas, R is the gas constant, and n is the number of moles of the gas. The most confusing thing about using the ideal law is making sure we use the right units when plugging in the numbers.
