gaseous state and ideal gas ?
Answers
Answer:
The kinetic theory of ideal gases makes 5 main assumptions:
The size of molecules is negligible compared with the mean intermolecular distance (i.e. they are widely spaced molecules).
Molecules move with different speeds and in random directions.
Standard laws of motion apply.
Collisions between molecules are elastic. Translational kinetic energy is not converted into other forms of energy.
There are no attractive intermolecular forces between molecules except during collision.
Limitations of the theory
Assumption 1: Real gaseous particles do have a volume.
Deviations large for large gas molecules (e.g. methane, carbon dioxide and ammonia). Deviations small for small gases (e.g. helium and hydrogen).
If the gas particles have a significant size compared to the total volume of the container, the volume
Answer:
gaseous state - the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily.
An ideal gas is a theoretical gas composed of many randomly moving point particles whose only interactions are perfectly elastic collisions. The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics.
