These observations are summarized by the equation of state for an ideal gas: PV=nRT Equation 1 where n is the number of moles of a substance. Charles's Law states that the volume of an ideal gas changes proportionally to the temperature of that gas, given that pressure and amount of gas present are held constant. After having a satisfactory result, record the volume of the air in the syringe and room temperature through a thermometer. Enjoy!
