The molecules of gas kept inside a closed container are shown in the figure.
What assumption can be made regarding the possibility of collision between gas molecules?
Important Questions on Gas Laws and Mole Concept
Write a short note on the given properties of a gas.
- Volume
- Pressure
- Temperature
A definite mass of a gas is kept in a closed cylinder is shown in figure A. Suppose the gas is transferred to the other cylinder without changing the temperature, as shown in Figure B. Is there any change in the number of molecules? What happens to the pressure when the volume is decreased?
Pull the piston of a syringe backwards. Press the piston by keeping its nozzle closed.
What changes can you observe in the volume of the gas inside the syringe?
What about decreasing the pressure?
What relation do you arrive at between pressure and volume of the gas?
The size of the air bubbles rising from the bottom of an aquarium increases. Can you explain the reason?
Take a dry bottle (an injection bottle) having a rubber stopper. Fix an empty refill through the rubber stopper. Fill a drop of ink into the lower end of the refill tube, then close the bottle. Dip this arrangement in lukewarm water.
What do you observe?
What is the reason for the rising of the ink upwards?
What did you observe on cooling the bottle after taking it out? Why?
From this, what can you infer about the relation between the volume and temperature of a gas?
Complete the table and show the relation between the volume and temperature at constant pressure.
| Volume V | Temperature T (In Kelvin scale) | |
| _____ |
