You cannot use a gas syringe for this experiment.
Think about what happens to the gas (air) inside the syringe when the temperature decreases. As the gas cools it will occupy a smaller volume and thus the syringe plunger will move DOWN the barrel.
It is used to hold a gas syringe in place when carrying out an experiment. The gas syringe will fill up with gas and you can read the amount of gas within it using the measuring lines. Hope it helped. Ask for any other queries that need answering.

Is it to push and pull the gas into the syringe or something else?

A gas syringe is basically a device that fills up with a gas that is produced and gives a volume for that gas. Gas from a reaction is forced into the syringe due to pressure and the syringe plunger is forced out (just like how you suck up a liquid with a normal syringe). It can be used to detect the volume of gas produced in a chemical reaction for instance.See the Web Links to the left for more information.
It everywhere in the air. In fact is takes up about 50% of the earth's atmosphere. Everytime you exhale, you are releasing carbon dioxide into the air while plants take this in for photosynthesis.

The fluid or gas inside the syringe will decrease in temperature, therefore it will decrease in volume. This will cause the syringe piston to slide inside the syringe. This is because of the ideal gas law: PV=nRT. If the pressure (P), the number of moles (n), and the ideal gas constant (R) remains constant, than the change in volume must be proportional to the change in temperature.
Carbon dioxide (CO2) is collected by downwards delivery because it is heavier than air. Almost all of our atmosphere is nitrogen (molecular mass = 28) and oxygen (molecular mass = 32), but CO2 has a molecular mass of 40.
A gas syringe is used to measure and dispense liquids or insert and withdraw a volume of gas. These syringes vary in sizes and can collect from 500 ml to 0.25 ml of gas.
Because ammonia is quite soluble in water, so that not all of the gas produced could be collected over water.
