Entropy: A 700-g quantity of an ideal gas undergoes a reversible isothermal compression at a temperature of 330 K. The compression reduces the volume of the gas from 0.40 m3 too 0.15 m3. The molecular mass of the gas is 38.0 g/mol. What is the entropy change for the gas during this compression? (R = 8.31 J/mol ? K)
A. -150 J/K B. -57 J/K C. 150 J/K D. 57 J/K E. 0 J/K
