DIRECTIONS: Read the question and select the best response.
An ideal gas initially at pressure P and volume V goes through the cycle shown in the P-V diagram. In terms of P and V, what is the net work done by the gas per cycle?
a pressure versus volume graph is given. the y-axis is labeled pressure and it has two tick marks. the first tick mark has value p and the second has value two p. the x-axis is labeled volume. it too has two tick marks. the first tick mark has value v and the second has value two v. the graph consists of a right triangle with vertices labeled a, b and c. each side of the triangle has an arrow denoting direction. vertex a of the triangle has coordinates v comma p. vertex b has coordinates two v comma two p. vertex c has coordinates two v comma p. side ab is the hypotenuse has an arrow at its midpoint indicating a direction from a to b. side bc is a vertical line segment that has an arrow at its midpoint indicating a direction from b to c. side ca is a horizontal line segment with an arrow indicating a direction from c to a.
