Gaseous State

1. At what condition the value of P xV is always constant?
2. Draw volume (V) and temperature (t°C) relationship of gases at constant pressure. Indicate the temperature at which the volume occupied by the gas becomes zero. Name that temperature.
3. What do you mean by ideal gas and real gas?
4. What is an ideal gas? Under what conditions will a gas behave nearly like an ideal gas?
5. State Dalton’s law of partial pressure.
6. What is universal gas constant?
7. State and explain Graham’s law of diffusion of gases.
8. 5 grams of hydrogen diffused through a porous membrane in 30 minutes. Find the time required to diffuse the same amount of SO2 gas at identical conditions.
