ing one mole of an ideal gas from a starting volume of 1L to

How much work is done reversibly compressing one mole of an ideal gas from a starting volume of 1L to a final volume of 250mL at a constant temperature of 293K? What is the change in entropy?
Solution:There is no change in temperature and therefore there is no change in internal energy .From the first law of thermodynamicNow, change in entropy is Ideal gas equation, So, . If then
