Question

The specific heat of hydrogen gas at constant pressure is $C subscript P equals 3.4 cross times 10 cubed cal divided by kg to the power of ring operator straight C$
and at constant volume is $C subscript V equals 2.4 cross times 10 cubed cal divided by kg to the power of ring operator straight C$ . If one kilogram hydrogen gas is heated from $10 to the power of ring operator straight C text to end text 20 to the power of ring operator straight C$ at constant pressure, the external work done on the gas to maintain it at constant pressure is

$10^{5} cal$
$10^{4} cal$
$10^{3} cal$
$5 \times 10^{3} cal$

The correct answer is: $10 to the power of 4 cal$
