Question

The heat energy q absorbed by a gas is equal to $\Delta H$ if heat is absorbed at a constant pressure.

• A. True
• B. False

Answer 1

The correct option is A True

$P=constant$

$\Delta P=0$

$\Delta W=P\Delta V$

$\Delta Q=n{C}_p\Delta T$

$\Delta H=\Delta U+P\Delta V$

$\Delta H=n{C}_v\Delta T+nR\Delta T=n{C}_p\Delta T$
