Two assumptions regarding the student's experiment are that the enclosure's volume and the amount of gas between trials will both stay constant in light of our understanding of the relationship between an enclosed gas's temperature and pressure. It is always possible to presume that the previously listed variables will not change while conducting an experiment to investigate the link between a gas's pressure and temperature. The learner will need to apply the Ideal Gas law formula in order to measure the needed data.
The first assumption is that the volume of the enclosure will remain constant throughout the experiment. This assumption is based on the understanding that the relationship between temperature and pressure is only valid when the volume of the gas remains constant. If the volume were to change between trials, it could introduce additional variables that could affect the observed pressure-temperature relationship.
The second assumption is that the amount of gas in the enclosure will also remain constant throughout the experiment. This assumes that there will be no leakage or addition of gas during the trials. This assumption is necessary to ensure that the only factor affecting the pressure-temperature relationship is the change in temperature, rather than changes in the amount of gas present.
In order to measure the data needed to investigate the relationship between pressure and temperature, the learner will need to apply the Ideal Gas Law formula. The Ideal Gas Law states that the pressure of a gas is proportional to its temperature, volume, and the number of moles of gas present. By manipulating the equation, the learner can calculate or measure the necessary values to establish the relationship between pressure and temperature.
