Question
Consider the following processes (all gases are ideal).a.) The pressure of 1 mole of oxygen gas is allowed to doubleisothermally.
b.) Carbon dioxide is allowed to expand isothermally to 10 timesits original volume.
c.) The temperature of 1 mol of helium is increased 25 degrees C atconstant pressure.
d.) Nitrogen gas is compressed isothermally to half its originalvolume.
e.) A glass of water loses 100 J of energy reversibly at 30 degreesC.
Which of these processes lead(s) to an increase in entropy?
Explanation / Answer
Entropy increases when carbon dioxide is allowed to expand and thetemperature rises at constant pressure. Increases in heat andvolume lead to more entropy, loss of pressure decreases entropy. Sob and c
