A student records $\Delta Q,\Delta U$ and $\Delta W$ for a thermodynamic cycle $A \to B \to C \to A.$ Certain entries are missing. Find correct entry in following options

  $AB$ $BC$ $CA$
$\Delta W$ $40\,J$   $30\,J$
$\Delta U$   $50\,J$  
$\Delta Q$ $150\,J$ $10\,J$  

 

  • A

    $W_{BC} = -70\, J$

  • B

    $\Delta {Q_{CA}} = 130\,J$

  • C

    $\Delta {U_{AB}} = 190\,J$

  • D

    $\Delta {U_{CA}} = -160\,J$
