1 Ideal Gas Law Apparatus TD‐8596A 1 Pressure Sensor – Absolute CI‐6532A 1 Analog Adaptor Introduction The purpose of this lab is to study the Ideal Gas Law to see how the pressure, volume, temperature, and amount of a gas effect one and another. The ideal gas law can be derived from basic principles, but was originally deduced from experimental measurements of Charles’ law (that volume occupied by a gas is proportional to temperature at a fixed pressure) and from Boyle’s law (that for a fixed temperature, the product PV is a constant).In the ideal gas model, the volume occupied by its atoms and molecules is a negligible fraction of V. The final law is Guy-Loussac’s Law, P1/T1 = P2/T2, the pressure is directly proportional to the temperature of an ideal gas when the volume is at a constant. Before we look at the Ideal Gas Equation, let us state the four gas variables and one constant for a better understanding.The four gas variables are: pressure (P), volume (V), number of mole of gas (n), and temperature (T). of moles of gas in the sample; T is the gas temperature (in Kelvins). Note that the units of R will allow the units of P, V, n and T in the Ideal Gas Law to cancel correctly. The ideal gas law is the equation of state of a hypothetical ideal gas (an illustration is offered in ). Thermodynamics and the ideal gas law Graph and calculation instructions NB.
In theory, an ideal gas would not have a volume or any intermolecular forces acting
