Question

there are only 5 molecules per cubic cm on average in a region of space where the temp is 3k. what will be the pressure of such fluid gas. (k= 1.38×10^-23 J/k)

Answer 1

Kinetic theory attempts to provide insight into the underlying microscopic basis for the macroscopically observed behavior of gases. In kinetic theory, a gas is assumed to consist of a very large number of molecules that move about randomly and collide frequently. At atmospheric pressure and room temperature, 1 cm3 of gas consists of approximately 3 x 1019 molecules. Although one cannot apply Newton’s laws to each molecule, one can relate the average value of certain quantities at the macroscopic level of quantities, such as pressure and temperature, that are observable at the macroscopic level.
