Question

The internal energy of 10g of nitrogen at ntp is about

Answer 1

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.

Hope it helps .
