Value of Gas Constant In its simplest form, matter exists in the gaseous state. Highly compressible, it is evenly dispersed with no fixed shape or volume, taking on whatever the container it's placed into holds. Its molecules interact very little, making gas highly mixable and responsive to certain laws that govern its behavior when exposed to different conditions such as pressure, temperature, and volume. These laws were developed based on the many experiments conducted concerning these properties.
The gas constant is a physical constant denoted by R and is expressed in units of energy per temperature increment per mole. It is also known as the ideal gas constant, the molar gas constant, or the universal gas constant. Unlike the Boltzmann constant, the gas constant value is expressed as a pressure-volume product instead of energy per unit increase in temperature per particle.Also Check - Malic Acid Formula

Boyle's Law - It demonstrates that as a gas's volume decreases, its pressure increases; mathematically, it is expressed as P being inversely proportional to V. Charles Law - It states that at constant pressure, an increase in temperature will cause the volume of a gas to expand - shown mathematically by V being proportional to T. Building upon these two laws, Avogadro's Law - This suggests that equal volumes of all gases, regardless of the number of molecules they contain, at the same temperature and pressure have the same amount.Also Check - Lead (II) Chloride Formula
Gay Lussac’s Law - It complements this by asserting that when the size remains fixed, a temperature change directly influences the pressure of any given mass of gas.Also Check - Periodic Acid formula
