What is a Carnot cycle? Obtain the expression for the efficiency of a reversible Carnot engineand starting from this expression state an appropriate statement of the second law ofThermodynamics.

A substance undergoes the cyclic process shown in the figure below. Work output occurs along path AB while work input is required along path BC, and no work is involved in the constant volume process CA. Energy transfers by heat occur during each process involved in the cycle.A pressure-volume graph consists of points and line segments plotted on a coordinate plane, where the horizontal axis is V (liters) and the vertical axis is P (atm). Three points are plotted:point A at (10.0, 5.00)point B at (50.0, 1.00)point C at (10.0, 1.00)Line segments connect the three points to form a triangle. Arrows along the line segments point from A to B, from B to C, and from C to A.(a) What is the work output during process AB? J(b) How much work input is required during process BC? J(c) What is the net energy input Q during this cycle? J

A gas follows the PV diagram in the figure below. Find the work done on the gas along the paths AB, BC, CD, DA, and ABCDA. (Enter your answers in J.)HINTThe area under the graph in a PV diagram is equal in magnitude to the work done on the gas. The work is positive if the gas is compressed and negative if it expands.Click the hint button again to remove this hint.A rectangular path is plotted on a PV diagram which has a horizontal axis labeled V (m3), and a vertical axis labeled P (105 Pa). The area inside the rectangle is shaded. The path is clockwise and runs through corner points A–D in the following order:A (1.00, 4.00), B (7.00, 4.00), C (7.00, 1.00), D (1.00, 1.00).(a)AB J(b)BC J(c)CD J(d)DA J(e)ABCDA J
