Escape velocity from the Moon is approximately 5310 miles per hour = 2.37 x 103 m/s. At certain spots on the surface of the Moon, the temperature of the surface material reaches 500 -600 K. Suppose a molecule of hydrogen (m = 3.33 x 10-27 kg) were to hit the surface of the Moon at 587 and reach a speed equal to the root-mean-square (rms) speed for this temperature. Calculate the rms of this molecule in order to escape the %3D atmosphere of the moon. (Boltzmann constant 1.38 x10-23 J/K). Notes: 1. Express answer in m/s 2. Do not write answer in scientific or exponential notation 3. Answer must be expressed with one (1) decimal place 4. Do not write the unit in the answer box
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.
