Q. An ideal monatomic gas initially has a temperature of 311 K and a pressure of 7.57 atm. It is to expand from volume 571 cm3 to volume 1390 cm3. If the expansion is isothermal, what are (a) the final pressure (in atm) and (b) the work done by the gas? If, instead, the expansion is adiabatic, what are (c) the final pressure (in atm) and (d) the work done by the gas

Q. A 0.30 kg softball has a velocity of 15 m/s at an angle of 35 degrees below the horizontal just before making contact with the boat. What is the magnitude of the change in momentum of the ball while in contact with the bat if the ball leaves with a velocity of (a) 20 m/s vertically downward, and (b) 20 m/s horizontally back toward the pitcher?
