To solve this problem, we will use the formula for work done during a reversible isothermal expansion of an ideal gas.The formula for work done during isothermal expansion is:Given:โข mole (since we have one mole of hydrogen gas)โข cal K molโข C K (since temperature must be in Kelvin)โข atmโข atmSubstitute these values into the formula:Simplify the expression:Recall that Thus, Using the approximate value caloriesSince the work done is negative (indicating work done by the system), caloriesTherefore, the correct option is Option 4: calories.
