Five 6 ohm resistors are connected in parallel. Which of the following is their effective resistance? A. 6 ohm
B. 1.2 ohm
C. 30 ohm
D. 5/6 ohm

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
