The ideal gas law actually combines a number of more specific observations regarding the behavior of gases. Which idea below is NOT supported by the ideal gas law? A) Boyle’s Law: for a fixed amount of gas at constant temperature, the volume is inversely proportional to its pressure. B) Van der Waals Rule: since gas particles of different gases have different sizes, the volume available to a gas depends on its identity. C) Charles’ Law: for a fixed amount of gas at constant pressure, the volume of a gas is directly proportional to its temperature. D) Avogadro’s Principle: at constant pressure and volume, all gases have the same molar volume (V/n).

What are the physical origins of the van der Waals parameters for describing a non-ideal gas? A) The value a corresponds to the change in entropy with respect to volume, while b corresponds to the change in energy with respect to entropy. B) The value b corresponds to the change in entropy with respect to volume, while a corresponds to the change in energy with respect to entropy. C) The value a corresponds to a reduction in the effective volume of the gas; b corresponds to a decrease in the effective pressure due to intermolecular forces. D) The value b corresponds to a reduction in the effective volume of the gas; a corresponds to a decrease in effective pressure due to intermolecular attractions.

What is Van Der Waals?

Van der Waals is a Dutch physicist and Nobel Prize winner who is best known for his work on the properties of gases. He developed an equation that explained how molecules interact with each other, which became known as the Van der Waals equation. This equation helped to explain why some gases behave differently than others at different temperatures and pressures. Additionally, his work contributed significantly to our understanding of thermodynamics and fluid dynamics.Van der Waals was born in 1837 in Leiden, Holland. He studied physics at the University of Leiden where he received his doctorate in 1873. After graduation, he began teaching at the same university but soon left for Berlin where he worked as a professor at the University of Berlin from 1877 until 1890 when he returned to Leiden for his final years as a professor there.In terms of research, Van der Waals made significant contributions in many areas including thermodynamics and statistical mechanics. In particular, he developed an equation (the Van der Waals equation) that could explain why some gases behaved differently than others under different conditions of temperature and pressure. His work also allowed us to better understand how particles interact with each other when placed under pressure or heat, leading to advances in fluid dynamics such as aerodynamics and hydrodynamics. In 1910, Van der Waals was awarded the Nobel Prize in Physics for his investigations into thermal equilibrium between heterogeneous substances effectively recognizing him for developing the Van der Waal’s equation which allows us to understand how molecules interact with each other under varying conditions of temperature and pressure. Van Der Walls’ work has had a far-reaching impact on modern science; it has improved our understanding about everything from aeronautical engineering to medicine thanks to its insights into intermolecular forces and thermodynamic behavior – all derived from his pioneering discoveries about molecular interactions over 140 years ago.
