In this experiment, a syringe is filled with a gas. The syringe has markings
on it to indicate the volume (in mL) of the gas in the syringe. You can choose
the gases you wish to investigate from the menu of available gases. Use the
volume slidebar to control the volume of the selected gas in the syringe. In
this experiment, the initial temperature of each gas is 25.0°C or 298K.
The needle on the syringe is plunged into an evacuated flask (a flask with no
air or other gas in it - a vacuum) and the gas starts to escape from the end
of the needle into the evacuated flask. You can time how long it takes for the
syringe plunger to move from the starting point (100.0 mL) to a point lower
on the syringe 0.0 mL.
