Pressure Concepts - Questions
The Pressure Concepts Concept Builder is comprised of 36 questions. The questions are divided into 14 different Question Groups and spread across three activities. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.
There are three activities in this Concept Builder. Those three activities are differentiated as follows:
- A Versus B: Question Groups 1-6 ... Given a comparison of two samples of gas based on four contrasting variables, the sample with the highest pressure must be determined.
- Pressure Units: Question Groups 7-10 ... Given a diagram of three pressure gauges utilizing three different pressure units (atm, psi, and mm Hg) for three different gas samples, the three samples of gas must be ranked according to their relatie pressure.
- Manometers: Question Groups 11-14 ... Given an open-end manometer diagram with mercury levels and height differentials and the atmospheric pressure, the pressure of the gas sample must be determined.
The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes.
