A cylinder-piston device contains argon confined by a 330 lbm frictionless plunger. For an interval of 2 min, a resistor located inside the cylinder receives a current of 6 A from an external 12 V battery. If the heat given by the gas is 2.50 Btu, determine the distance traveled by the plunger in in. The area of the plunger is 5.0 in ^2, the atmospheric pressure acting on the outside of the plunger is 14.4 psia and the local gravity is 31.0 ft/s^2.

3. There is an abnormal gas in the cylinder. It is compressed from a volume of 300 (liters) and a pressure of 0.1 MPa to a volume of 1000 and a pressure of 0.7 MPa. When the state of the gas can be described by the relation of'PI = constant', find the value of n and the work done by the gas (kJ).
Two electric pumps are being used to pump water to a cistern at the top of a 50 meter hill. A meter is used to measure the electrical energy in kWh consumed by both pumps over a six-hour period. Both pumps consume the same kWh of electrical energy over the pumping period. If we know that pump #1 has an efficiency of 40% and pump #2 has an efficiency of 80%, what can we say about the volume of water moved by each pump? Assume both pumps use the same piping system, so hydraulic frictional losses are the same for both pumps. pump #1 moved twice as much water as pump #2 pump #2 moved twice as much water as pump #1 both pumps moved the same amount of water

Figure 1 shows a piston-cylinder assembly containing gas, on top of a hot plate. At the beginning, the system is at room temperature, and the piston seats on the set of stops. Then, the heating plate is turned on and eventually the piston starts to rise. Determine at which pressure this happens, considering that g = 9.81 m/s 2.
There is a piston-cylinder assembly with a mass of 50 kg and a surface area of 0.01 m2. The mass of air is 5 g. The initial volume of air is 5 liters. Atmospheric pressure is 100 kPa. As the specific internal energy of the air decreases by 260 kJ/kg the volume of air is also gradually decreasing to 0.002 m3. Ignore friction that is between the piston and the cylinder surface. Determine the heat transfer to the air. (kJ)
