A horizontal piston/cylinder arrangement is placed in a constant-T bath. The piston slides in the cylinder with negligible friction, and an external force holds it in place against an initial gas pressure of 16 bar. The initial gas volume is 0.04 m^3. The external force on the piston is reduced gradually, and the gas expands isothermally as its volume doubles. If the volume of the gas is related to its pressure so that the product PV^t is constant, what is...

A horizontal piston/cylinder arrangement is placed in a constant temperature bath. The piston slides in the cylinder with negligible friction, and an external force hold it in place against an initial gas pressure of 1 bar. The initial gas volume is 0.04 m^3. The external force on the piston is reduced gradually, and the gas expands isothermally as its volume triples. (a) If the volume of the gas is related to its pressure so that the product PV^t is constant,...

4) The work produced by a piston-cylinder device depends on the pressure inside the cylinder and the amount the piston moves, resulting in a change in volume inside the cylinder. Mathematically In order to integrate this equation, we need to understand how the pressure changes with the volume. We can model most combustion gases as air and assume that they follow the ideal gas law PV- nRT where P- pressure, kPa, volume, m n- number of...

Consider a Carnot cycle in which the working substance is 0.10 mol of perfect gas molecules, the temperature of the hot source is 373 K, that of the cold sink is 273 K; the initial volume of gas is 1.00 dm', which doubles over the course of the first isothermal stage. For the reversible adiabatic stages it may be assumed that VT3/2 = constant. a) calculate the volume of the gas VB and Vc); b) calculate the volume of the...

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...

400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3. (a) Draw a P-V diagram for this process. (b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion? (c) Calculate the work done by the gas. (d) Calculate...

A 19.0- L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.2 atm . Enough weight is suddenly removed from the piston to lower the external pressure to 1.6 atm . The gas then expands at constant temperature until its pressure is 1.6 atm . The change in the internal energy of a system, ΔE , for an isothermal expansion of an ideal gas is 0. Use this information in your calculations...
