5 Questions
Explain the characteristics of an ideal gas and provide an example of a real gas.
An ideal gas follows the gas laws at all pressure and temperatures, obeys the ideal gas equation PV=nRT, has negligible intermolecular interactions, and has very small particle volume. Oxygen, nitrogen, and air are considered real gases as they obey gas laws within certain temperature limits.
Define an ideal gas and explain why it is considered hypothetical.
An ideal gas is a perfect gas that follows Boyle's law and Charles' law, with its characteristics equation obtained by the combination of these laws (PV=RT) at all pressure and temperature. It is considered hypothetical because there is no perfect gas in nature.
What are the differences between an ideal gas and a real gas?
An ideal gas obeys gas laws under all pressure and temperature, follows the ideal gas equation PV=nRT, has negligible intermolecular interactions, and has very small particle volume, while a real gas obeys gas laws only under low pressure and temperature, does not obey the ideal gas equation, and has non-negligible particle volume compared to the total volume of gas.
Discuss the existence of ideal gases in nature.
There is no perfect gas in nature, and ideal gases are considered hypothetical. Real gases, such as oxygen, nitrogen, and air, are considered as perfect gases as they obey gas laws within certain temperature limits.
Explain the conditions under which real gases are considered perfect gases.
Real gases, such as oxygen, nitrogen, and air, are considered perfect gases as they obey gas laws within the temperature limits of thermodynamics, specifically under low pressure and temperature.
