Helium gas at 105.0 kPa and 309.0K is located within a cylinder with a piston. Initially the gas occupies 0.4000 m. While a constant force, F, is applied to the end of the piston so that the pressure inside the cylinder is held constant at 105.0 kPa, 5090.0 J of heat is transferred to the helium gas. The specific enthalpy of helium gas is given by the approximate relation: (kJ/mol) = 0.02087(K) Q=5090.0J Final Conditions P2 = 105.0 kPa Initial...

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...

As shown in the figure below, a gas contained within a piston-cylinder assembly, initially at a volume of 0.1 m3, undergoes a constant-pressure expansion at p 2 bar to a final volume of V2 0.2 m3, while being slowly heated through the base. The change in internal energy of the gas is 0.25 kJ. The piston and cylinder walls are fabricated from heat-resistant material, and the piston moves smoothly in the cylinder.

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...
