Assuming the gas molecules can be approximated as small spheres of diameter 2.5x100 m, determine the fraction of the volume found in part A that is occupied by the molecules. Express your answer using two significant figures.
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.
![IP A gas has a temperature of 310 K and a
pressure of 105 kPa
Part A
Find the volume occupied by 1.50 mol of this gas, assuming it is ideal.
Express your answer using three significant figures.
Vgas 3.68x102 m²
Submi
Part B
Correct
Correct answer is shown. Your answer 0.037 m² was either
rounded differently or used a different number of significant
figures than required for this part.
Important: If you use this answer in later parts, use the full
unrounded value in your calculations.
