Which of the following statements is not true according to kinetic theory? a. The molecules in an ideal gas undergo elastic collisions. b. The molecules in an ideal gas only interact during collisions. c. Electrical attractions and repulsions between the molecules must be accounted for in the total energy of the ideal gas. d. The average energy of a molecule in an ideal gas is evenly distributed between the different degrees of freedom of the molecule. e. The energy of an ideal gas only depends on the kinetic energy of the gas.
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.
