Estimate the average thermal energy of a helium atom at (i) room temperature `(27^(@)C)`. Boltzmann constant `=1.38 xx 10^(-23) JK^(-1)`

Estimate the average thermal energy of a helium atom at room temperature (27 ^@C)

The pressure exerted by an ideal gas is P = (1)/(3) (M)/(V)C^(2) , where the symbols have their usual meaning. Using standard gas equation, PV = RT, we find that C^(2) = (3 RT)/(M) or C^(2) oo T . Average kinetic energy of translation of one mole of gas =(1)/(2) MC^(2) = (3 RT)/(2) with the help of the passage given above, choose the most appropriate alternative for each of the following quetions : Average thermal energy of a helium atom at room temperature (27^(@)C) is Given, Boltzmann constant k = 1.38 xx 10^(-23) JK^(-1) :

The average thermal energy of a oxygen atom at room temperature ( 27^(@)C )

Estimate the average thermal energy of helium atom at a temperature of 27° C . [Boltzmann constant is 1.38×10^(-23) J/K ].

The pressure exerted by an ideal gas is p= 1/3 M/Vc^2 where the symbols have their usual meanings. Using standard gas equation, pV=nRT we find that c^2=(3RT)/M or C^2 prop T . Average kinetic energy of translation of 1 mol of gas= 1/2 Mc^2=(3RT)/2 Average thermal energy of a helium atom at room temperature (27^@C) is (given Boltzmann constant k=1.38 times 10^-23 J.K^-1 )
