As a fixed amount of ideal gas in a cylinder expands, its pressure decreases according to the formula: p(V)=(10.2atm)e^ -0.42V, where V is in liters and p is in atmospheres. a) What are the units of the constant -0.42 in the exponent? b) If the initial volume is 2.5 liters and the final volume is 7.5 liters, what is the magnitude of the work done by the gas during the expansion?

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?...
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...
To practice Problem-Solving Strategy 19.1 Work in Ideal-gas Processes. A cylinder with initial volume V contains a sample of a gas at pressure p. On one end of the cylinder, a piston is let free to move so that the gas slowly expands in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V and pressure 3p, the piston is pushed in so that the gas is compressed isobarically to its...
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...
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.

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 piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p1 = 60 lbf/in.and T1 = 90°F to a final state where P2 = 10 lbf/in. During the process, the pressure and specific volume are related by pr2 = constant. Determine the energy transfer by work, in Btu. W = Btu the tolerance is +/-2%
