During an isothermal expansion of an ideal gas its

Options

A. Intemal energy increases
B. Enthalpy decreases
C. Enthalpy remains unaffected
D. Enthalpy reduces to zero

Answer

C

Explanation

During isothermal expansion ideal gas, `Delta T= 0`
`Delta H= Delta E + P Delta V= Delta E + n_(g)R Delta T= 0+0=0`
