Maximum work that could be secured by expanding the gas over a given pressure range is the __________ work.

A Isothermal
B Adiabatic
C Isentropic
D None of these

Correct Answer: Isothermal

The isentropic process is nothing but reversible adiabatic process since between the isothermal and adiabatic process the isothermal process has maximum area under $$P-V$$  diagram the isothermal process will have maximum work done during expansion. Since the slope of $$p-v$$   plot for adiabatic process is greater than isothermal process.

STP-তে একটি আদর্শ গ্যাসকে প্রথমে তার প্রাথমিক আয়তনের এক-তৃতীয়াংশে সংকুচিত করা হয়, এবং তারপর প্রসারিত হতে দেওয়া হয় যতক্ষণ না তার চাপ প্রাথমিক চাপের অর্ধেক হয়। উভয় প্রক্রিয়ায় গ্যাসের তাপমাত্রা স্থির থাকে। যদি গ্যাসের প্রাথমিক অভ্যন্তরীণ শক্তি । হয়ে থাকে তাহলে এর চূড়ান্ত অভ্যন্তরীণ শক্তি কত?
