distinguish between ideal gas and real gas
Answers
Answer:
Ideal gas:
An ideal gas is defined as a gas that obeys gas laws at all condition of pressure and temperature. Ideal gases have velocity and mass. They do not have volume. When compared to the total volume of the gas the volume occupied by the gas is negligible. It does not condense and does not have triple point.
Real gas:
A real gas is defined as a gas that does not obey gas laws at all standard pressure and temperature conditions. When the gas becomes massive and voluminous it deviates from its ideal behaviour. Real gases have velocity, volume and mass. When they are cooled to their boiling point, they liquefy. When compared to the total volume of the gas the volume occupied by the gas is not negligible.
Answer:
Ideal Gas Real Gas
1) Ideal gas obeys all gas laws under all conditions of temperature and pressure. 1) Real gas obeys gas laws at low pressure and high temperature.
2) The volume occupied by the molecules is negligible as compared to total volume. 2) The volume occupied by molecules is not negligible as compared to total volume of gas.
3) The force of attraction among the molecules are negligible. 3) The force of attraction are not negligible at all temperatures and pressures.
