Suppose 1.0 mol of a monatomic ideal gas initially at 10 L and 307 K is heated at constant volume to 614 K, allowed to expand isothermally to its initial pressure, and finally compressed at constant pressure to its original volume, pressure, and temperature.
(a) What is the net energy entering the system (the gas) as heat during the cycle? J
(b) What is the net work done by the gas during the cycle? J
(c) What is the efficiency of the cycle? %
Space invaders land on earth. On the invaders' temperature scale, the ice point is at 25°I (I = invader), and the steam point is at 153°I.

An airplane must reach a speed of 189mi/h to take off. If the runway is 472m long, what is the minimum value of acceleration that will allow the airplane to take off successfully.
An object moving with uniform acceleration has a velocity of 10.0 cm/s in the positive x-direction when its x-coordinate is 3.09 cm. If its x-coordinate 3.05 s later is ?5.00 cm, what is its acceleration?
If a car travelling at 30m/s will skid 18.00 m when its brakes lock and the car slides, how far would it skid if it is travelling at 40 m/s when its brakes lock? (This question is typical on some driver's license exams. Note: 10 m/s = 22 mph)
