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.

volume must be constant. number of moles must be constant.

Well, assuming the student isn't planning to summon the fiery depths of the sun in their classroom, two assumptions they must make are that the gas behaves ideally (meaning it follows the ideal gas law) and that no leaks or loss of gas will occur during the experiment (or else it'll be a real gas-tastrophe!).

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

In order to study the relationship between temperature and pressure of an enclosed gas, two assumptions that must be made are: First, the volume of the gas remains constant throughout the experiment, and second, the gas behaves ideally and follows the gas laws accurately.
