What is the Ideal Gas Law?
The ideal gas law, PV=nRT, is a mathematical equation that describes the relationship between the pressure, volume, moles of gas, and the universal gas constant. The equation can be represented by the equation PV=nR T, where n is the number of moles of gas and R is the universal gas constant.
In this equation, P represents the pressure of the gas, V represents the volume of the gas, n represents the number of moles of gas, n * R represents the number of moles of moles of gas at constant pressure (n2), and T represents temperature. This equation can be used to calculate the properties of a gas subject to pressure, temperature, or volume changes.
The ideal gas law was first proposed by scientist Robert Boyle in 1784
. Based on his experiments with air pressure and volume in a closed container and constant temperature over a period of time, Boyle proposed that if we take a constant amount of air and increase its volume but keep its pressure constant over time then we would see an increase in temperature just as we would with an ideal gas.
Charles’s law (also known as Gay-Lussac’s law) proposed in 1808 adds another factor to the equation: The amount of energy required to increase the volume of a given mass of a substance is directly related to its temperature. Using Charles’s law enables us to quantify how much energy is required to change the volume of a substance at constant temperature.
Other things you should keep in mind is kinetic theory of gases. - collisions of gas particles with the container walls are elastic
- there are no forces of attraction or repulsion between gas particles
- all collisions are perfectly elastic
From these premises, we can derive the ideal gas law: PV = nRT.
Boyle's law states PV = k
Where pressure P, V is volume and k is a constant. This equation relates the pressure and volume of a gas at constant temperature. If the temperature of the gas increases, the kinetic energy of the particles also increases. The increased kinetic energy causes more collisions between particles and thus results in an increase in pressure.
The ideal gas constant R = 8.314 moles -1 K -1 is a constant that relates the molar gas constant to the number of molecules in one mole of a gas and the Boltzmann constant. The value of R can be used to convert units of pressure, volume, or temperature. For example, if we want to convert 2 atm into pascals (Pa), we would use the equation:
P(Pa) = 2 atm x 101325 Pa/atm
= 2 x 101325 Pa
= 20265000 Pa
Note: The SI units of the gas constant is pascal.
Lastly, the perfect gas law is an equation of state for a gas that relates the pressure, volume, and temperature of a gas. The perfect gas law is PV = nRT, where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas present, R is the universal gas constant, and T is absolute temperature.

How to Calculate Volume, Pressure, Moles and Temperature
The ideal gas law equation can be used to calculate the pressure, volume, moles and temperature of an ideal gas. The equation is a way of describing how the particles in a gas move around. It states that the pressure of a gas decreases with increasing volume, the temperature of gas increases with increasing pressure, the number of moles of gas increases with increasing temperature, and the total amount of gas held constant.
This equation can be rewritten as:
Pr= pV+ nT+ nP + nA
The universal gas constant (R) and Boltzmann constant (k) are important for calculations. R is the constant for gas molecules and k is the constant for particles in a given volume of gas. When using the equation, it’s important to understand the characteristics of an ideal gas. For example, gases at room temperature have a constant pressure of 1 atm and a warmer gas has a higher pressure.
Step-by-Step Guide to Ideal Gas Law Calculations
The Ideal Gas Law equation is, PV = NRT, where
- P is the pressure, V is the volume
- N is the number of moles of gas
- R is the universal gas constant
- T is the absolute temperature.
The equation can be used to calculate the volume of a given amount of gas at constant pressure if the number of moles of gas and the temperature are known. This equation can also be used to calculate the volume of gas at constant pressure given the number of moles of gas and temperature.
Calculations using Charles' Law involve a change in either temperature (T2) or volume (V2) from a known starting amount of each (V1 and T1). Avagadro's Law gives the relationship between volume and amount of gas when pressure and temperature are held constant.
By knowing these formulas and using them in calculations, you can get accurate results for many applications involving gases.
