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,...
5. Consider the following piston-cylinder arrangement which is thermally insulated. Initially, the same 1 mole of monoatomic ideal gas are confined in the cylinder A and B respectively which are partitioned by a thermally conducted metal plate as shown in Figure 1. The initial volume and absolute temperature (X) of two partitions are the same as V and T respectively and the external pressure of the cylinder is given by P, as shown in Figure 1. When heat (g) was...
visual studio 2017 c++ 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...
105Pa, initial temperature T-300K, and an initial 1. An ideal gas with initial pressure 2 volume V - 1m3 expands isothermally to a final volume of 2m3. Then, the gas returns to its initial state, first by constant pressure (isobaric) contraction, and then by a change at constant volume (isochoric) a) Draw a PV diagram of this process. What's the total change in thermal energy of the entire process? b) What's the work done by the environment on the gas?...
7.) One mole of an ideal gas is contained in an insulated piston-cylinder arrangement in an initial state T, P,V. The gas is allowed to expand adiabatically and irreversibly against a constant external pressure P. until a point is reached where the internal pressure becomes equal to Po. If C for the gas is constant and equal to 1.5 R, derive an expression giving the final temperature of the gas in terms of P., V, T, and R.
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...

A piston with a radius of 2.5 cm is placed into a cylindrical tube a distance of 4.5 cm from the closed end of the tube, holding in a quantity of air. The piston is attached to a spring with a spring constant of 324 N/m. The other end of the spring is attached to a rigid wall. The tube is surrounded in ice water which keeps the gas at a temperature of o°C. Initially, the spring is relaxed, and...
