In an adiabatic process, δ H=0 And according to first law of thermodynamics δ H=δ U+W ∴ W=-δ U

Statement 1 is true, Statement 2 is true. Statement 2 is a correct explanation o f Statement 1

Statement 1 is true, Statement 2 is false

Statement 1 is false, Statement 2 is true

Statement 1 is false, Statement 2 is true. Statement 2 is not a correct explanation of Statement 1

In an adiabatic process, δH=0 And according to first law of thermodynamics δH=δU+W ∴W=−δU

In an adiabatic process, $δH = 0$ And according to first law of thermodynamics
$δH = δ U + W$
$∴ W = - δ U$
