Question

The relation between $\Delta Eand\Delta H$ is

• A. $\Delta H=\Delta E-P\Delta V$
• B. $\Delta H=\Delta E+P\Delta V$
• C. $\Delta E=\Delta V+\Delta H$
• D. $\Delta E=\Delta H+P\Delta H$

Answer 1

The correct option is B $\Delta H=\Delta E+P\Delta V$

$\Delta H=\Delta E+P\Delta V$ Remember, from the first law of thermodynamics, $\Delta E=q+w,w=-P\Delta V,q_p=\Delta H;\Delta H=\Delta E+P\Delta V$
