A container with an initial volume of 0.0607 m³ holds 2.45 moles of a monatomic ideal gas at a temperature of 325 K. The gas is now compressed adiabatically to a volume of 0.0377 m³. Find (a) the final pressure and (b) the final temperature of the gas. 3. (a) Calculate the change in entropy when a 0.125-kg chunk of ice melts at 0°C. Assume the melting occurs reversibly. (b) Suppose heat is now drawn reversibly from the 0° meltwater, causing a decrease in entropy of 112 J/K. How much ice freezes in the process?

Transcribed Image Text:A container with an initial volume of 0.0607 m³ holds 2.45 moles of a monatomic
ideal gas at a temperature of 325 K. The gas is now compressed adiabatically
to a volume of 0.0377 m³. Find
(a) the final pressure and
(b) the final temperature of the gas.
3. (a) Calculate the change in entropy when a 0.125-kg chunk of ice melts at 0°C.
Assume the melting occurs reversibly.
(b) Suppose heat is now drawn reversibly from the 0° meltwater, causing a
decrease in entropy of 112 J/K. How much ice freezes in the process?
