Grens Chem Blog: March 2013

Today we explored the inverse relationship between Pressure and Volume of a gas using plastic syringes. We experienced this relationship by feeling the "push" and "pull" against the gas molecules both inside the syringe and outside, saw this visually using marshmallows inside the syringe, and also used the Logger Pro software and Vernier Gas Pressure sensors to graph this relationship.

GAS LAWS AND RELATED PROBLEMS - schoolbag.info

TYPE PROBLEM: The volume of a gas at 780. mm pressure and 30.°C is 500. mL. What volume would the gas occupy at STP? You again can use reasoning to determine the kind of fractions the temperatures and pressures must be to arrive at your answer. Since the pressure is going from 780. mm to 760. mm, the volume should increase.
