Chapter 14, Problem 26 GO The drawing shows an ideal gas confined to a cylinder by a massless piston that is attached to an ideal spring. Outside the cylinder is a vacuum. The cross-sectional area of the piston is A = 2.50 x 103 m². The initial pressure, volume, and temperature of the gas are, respectively, Po, Vo = 6.00 x 10-4 m and To = 273 K, and the spring is initially stretched by an amount Xo = 0.097...

1. The drawing shows an ideal gas confined to a cylinder by a
massless piston that is attached to an ideal spring. Outside the
cylinder is a vacuum. The cross-sectional area of the piston is A =
2.50 × 10-3 m2. The initial pressure, volume, and temperature of
the gas are, respectively, P0, V0 = 6.00 × 10-4 m3 and T0 = 273 K,
and the spring is initially stretched by an amount x0 = 0.092 m

1. Manufacturers of headache remedies routinely claim that their
own brands are more potent pain relievers than the competing
brands. Their way of making the comparison is to compare the number
of molecules in the standard dosage. Tylenol uses 325 mg of
acetaminophen (C8H9NO2) as the
standard dose, while Advil uses 2.00 x 102 mg of
ibuprofen (C13H18O2). Find the
number of molecules of pain reliever in the standard doses of (a)
Tylenol and (b) Advil.

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. Starting from the final state of the He gas in part (b), the gas (and apparatus) was cooled from 298 K to 263 K. The...

One mole of ideal gas is confined in a cylinder by a piston and is in the thermal contact with a heat reservoir with T=To. As a result, gas slowly expands from V1 to V2 while at the same temperature To. The internal energy of the gas does not change. Calculate work done by the gas and the heat flow into the gas.

He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. The mechanical stop is a nut on a threaded rod that can be turned, slowly allowing the gas in the cylinder to expand. This process...

1. A gas fills the right portion of a horizontal cylinder whose radius is 5.50 cm. The initial pressure of the gas is 1.01 x 10' Pa. A frictionless movable piston separates the gas from the left portion of the cylinder, which is evacuated and contains an ideal spring, as the figure shows. The piston is initially held in place by a pin. The spring is initially unstrained, and the length of the gas-filled portion is 23.0 cm. When the...

A movable piston traps 0.205 moles of an ideal gas in a vertical cylinder. As the temperature of the gas is decreased from 511 ◦C to 24.0◦C, the piston slides without friction, reducing the volume of the gas so that its pressure remains constant. Find the work (J) done on the gas in the piston. Hint: Use the ideal gas law to change W = −P∆V to an expression using n and T. Be sure to include the sign of...
