Question

If is speed of molecules in a gas and is the speed of sound waves in the gas, the value of for all diatomic gases, is

Answer 1

Answer:

If c is r.m.s speed of molecules in a gas and upsilon is the speed of sound waves in the gas, show that c//upsilon is contant and independent of temperature for all diatomic gases. As γ is constant and independent of temp. ∴cυ= constant and independent of temp. ∴cυ=√31.4=1.46=a constant.
