When we held the temperature constant and cut the volume in half, each time we reduced the volume we observed that the pressure (increased/decreased) by a factor of (1 / 2 / 4 /8 / 10). Circle the correct answer.

When we held the temperature constant and reduced the volume from 10 to 1, we observed that the pressure (increased/decreased) by a factor of ( 1 / 2 / 4 / 8 / 10). Circle the correct answer.

(a.) We observed that as we compress the gas (decrease the volume) the temperature (increased/decreased) and pressure (increased/decreased). Circle the correct answers.

(b.) We observed that as we compress the gas (decrease the volume) the molecules moved (faster/slower) Circle the correct answer.

(c.) As we compressed the gas the temperature (increased/decreased) and kinetic energy of the molecules (increased/decreased) and the molecular activity (increased/decreased). Circle the correct answers.

Solution Summary

Questions are related to the observations made during a lab experiment to demonstrate the Ideal Gas Law. Experiment has been performed at constant volume (iso-choric), constant pressure (iso-baric) and constant temperature (iso-thermal). I have answered nine questions in all.
