A student wants to perform an experiment to study the relationship between the temperature and pressure of an enclosed gas. In one or two sentences, describe two assumptions that must be made in performing this experiment.

Two assumptions that must be made in performing this experiment are that the gas behaves ideally and that the volume of the gas remains constant.

Two assumptions that must be made in performing this experiment are: (1) the gas behaves ideally, following the ideal gas law, and (2) the volume of the gas remains constant during the experiment.

Two assumptions that must be made in performing this experiment are: first, the volume of the gas remains constant throughout the experiment, and second, the amount of gas (moles) remains constant.
