A cylinder with a 16-cm-diameter piston contains gas at a pressure of 3.0atm. a) How much force does the gas exert on the piston? b) How much force does the environment exert on the piston? c) The gas expands at constant pressure and pushes the piston out 10cm. How much work is done by the environment? d) How much work is done by the gas?
A gas is confined within a piston-cylinder device. The piston rests, stationary atop the gas and has a mass of 6.3 kg and a cross sectional area of 550 mm^2. If atmospheric pressure is 104 kPa, determine the gage pressure of the gas in the cylinder and the absolute pressure of the gas in the cylinder.
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 piston-cylinder of gas with a pressure of 45 psi is compressed from 25 gal to 20 gal at the same time it is heated from a temperature of 300 K to 360 K. What is the new pressure inside the cylinder? Need to show all referents in unit conversions.
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...
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. The local atmospheric pressure is 1 bar. Piston-...
* A gas is contained in a vertical, frictionless piston-cylinder device. The piston has a mass of 2 kg and a cross-sectional area of 30 cm2. A spring above the piston is compressed by 2.5 mm and has a spring constant, k, of 38 kN/m. a. If the atmospheric pressure is 1 atm, determine the initial pressure (P1) inside the cylinder. Heat is added to the system until the piston moves an additional 10 mm. b. How much did the...
Helium gas at 113.0 kPa and 426.0 K is located within a cylinder with a piston. Initially the gas occupies 0.3400 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 113.0 kPa, 7060.0 J of heat is transferred to the helium gas. The specific enthalpy of helium gas is given by the approximate relation: HkJ/mol) = 0.02087(K) Q=7060.0J > F- Final Conditions P2 =...
One kilogram of water vapor as an ideal gas is contained in a piston. cylinder system at a pressure of 1 bar and a temperature of 120 C. It is compressed adiabatically and irreversibly up to 200 bar. Calculate the work done by the vapor in kJ.
Two mole of ideal gas, is compressed adiabatically in a piston/cylinder device from 2 bar and 25oC to 7 bar. The process is irreversible and requires 25% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas? Assume Cv=(5/2)R in this calculation.
