Kinetic Energy would have to be the answer. Pretty sure.
Ideal gas law:
PV = nRT
P = pressure, V = volume, n = # of moles, R = gas constant, T = temperature
Equipartition theorem:
Each degree of freedom that a molecule has adds 0.5kT to its total internal energy where k = Boltzmann's constant and T = temperature
2nd law of thermodynamics:
A set of governing principles that restrict the direction of net heat flow (always hot to cold, heat engines are never 100% efficient, entropy always tends to increase, etc)
Clearly the answer is Choice A
pitch goes up on approach ... Doppler effect
Answer: Kinetic Molecular Theory claims that gas particles are in continuous motion and completely demonstrate elastic collisions. Kinetic Molecular Theory can be used to describe the rules of both Charles and Boyle. A series of gas particles only has an average kinetic energy that is directly proportional to absolute temperature.
