One mole of an ideal gas with

\gamma = 1.4,

is adiabatically compressed so that its temperature rises from

27^\circ C

35^\circ C,

. The change in the internal energy of the gas is

\left( {R = 8.3J/mol.\,k} \right)

View answer and explanation

Correct option: B

166 J

Option B (166 J) is correct because it is the change in internal energy calculated using the given temperature change and the number of moles.
