A balloon contains two gases: oxygen and nitrogen. According to the second law of thermodynamics, which event can never occur spontaneously? A) molecules of the two gases mixing evenly throughout the balloon B) molecules of the two gases leaking out small openings in the skin of the balloon C) molecules of the two gases traveling at a variety of speeds D) molecules of the two gases separating to opposite ends of the balloon
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
