An ideal gas is a hypothetical gas made of numerous arbitrarily moving point particles that are not under the influence of interparticle interactions. Ideal gas laws are the laws which are concerned with ideal gases. These laws were determined by Boyle and Charles (Boyle’s law and Charles’s law, respectively). Generally, an ideal gas law is an equation that describes the state of a theoretical ideal gas. It is a satisfactory approximation of the properties of various gases under numerous physical conditions, although it has many constraints.

Pressure of Ideal Gas Questions and Answers
1) What is meant by pressure?
Pressure is defined as the force exerted perpendicular to the surface of a body per unit area (the region where force is applied). Gauge pressure is a type of pressure relative to normal atmospheric pressure. Several units are used to denote pressure. Few of the units arise from a force unit divided by an area unit. The pascal (Pa) is the SI unit of pressure (N/m2 or newton per square metre).
2) What is meant by an ideal gas?
An ideal gas is a hypothetical gas made of numerous arbitrarily moving point particles that are not under the influence of interparticle interactions. These laws were determined by Boyle and Charles (Boyle’s law and Charles’s law, respectively). The ideal gas idea is helpful because it follows the ideal gas laws, a fundamental equation of state, and is receptive to examination under statistical mechanics.
3) What are the ideal gas laws?
Ideal gas laws are the laws which are concerned with ideal gases. These laws were determined by Boyle and Charles (Boyle’s law and Charles’s law, respectively).
Boyle’s law describes that for a particular mass of gas existing at a stable temperature, its pressure is inversely proportional to the volume of the gas.
Charles’s law describes that for a particular fixed gas mass existing at constant pressure, the volume of the gas is directly proportional to the temperature of the gas.
4) Explain the ideal gas equation.
The Ideal gas law is the equation of the state of a hypothetical ideal gas. It is a satisfactory approximation of the properties of various gases under numerous physical conditions, although it has many constraints. The ideal gas equation can be expressed as,
PV = nRT
5) Give some ideal gas examples.
Several gases such as hydrogen, oxygen, nitrogen, noble gases, carbon dioxide, and other air mixtures can be considered ideal gases within some tolerances under a fixed parameter range around basic pressure and temperature.
6) What is the formula for finding the pressure of an ideal gas?
7) What are the ideal gas law units?
In the case of the gas constant of R = 0.082 L.atm/K.mol, pressure should be in atmospheres atm units, temperature T in kelvin K and volume in litres L.
In the case of the gas constant of R = 8.31 J/K.mol, pressure P should be used in the pascals Pa units, temperature T in kelvin K and volume in litres L.
8) The _________ is also called the molar gas constant or ideal gas constant, or universal gas constant.
Answer: Gas constant
Explanation: The gas constant is also called the molar gas constant or ideal gas constant, or universal gas constant.
9) Which are laws that are incorporated in the ideal gas equation?
The ideal gas equation is the amalgamation of basic laws like Boyle’s law, Gay-Lussac’s law, Charle’s law, and Avogadro’s law.
10) What is meant by the ideal gas state?
In this state, the pressure, volume and temperature of a gas are directly related to each other.
