Q1. Find out the work for an isothermal expansion of 3.50 mol of an ideal gas at temperature of 19 oC from pi = 5.43 atm to pf = 2.74 atm.
Q2. A small ball of 53 grams is suspended from a string of length 86 centimeters and whirled in a circle lying in the horizontal plane. If the string makes and angle of 31 degrees with the vertical, find out the centripetal force experienced by the ball. The acceleration of gravity is 9.8 meters per second squared. Respond in the unit of Newtons.
