Water at 68 degrees f is in a long, rigid cylinder of inside diameter 0.600 in. A plunger applies pressure to the water. If, with zero force, the initial length of the water column is 25.00 in, what will it's length be if a force of 420lbs is applied to the plunger. Assume no leakage and no friction. If the plunger is held fixed and the water temperature is increased by 100 degrees f, what is the force acting on the plunger?
