At N.T.P., Temperature(T) = 273 K.
Universal Gas Constant(R) = 8.31 J/molK.
Using the Formula,
Internal Energy = n × f/2 × RT
where, n is the no. of moles.
No. of moles of the Nitrogen = 10/28 = 0.36 moles.
Degree of Freedom of Nitrogen = 5 (since, it is an diatomic gas.)
∴ Internal Energy = 0.36 × 5/2 × 8.31 × 273
∴ Internal Energy = 0.9 × 8.31 × 273
∴ Internal Energy = 2041.767 J.
