Use the following information as needed to calculate the amount of work done on a gas in the “compression stroke” of a piston. How much is the net work done by the gas, and what is the efficiency?
Pressure = 15.6 atm
Total volume of the cylinder = 542 mL
Clearance volume = 42 mL
0.0177 mol gas mixture
0.0641 g gas mixture

* 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...
1) An ideal gas is enclosed in a cylinder with a movable piston
on top of it. The piston has a mass of 8,000 g and an area of 5.00
cm2 and is free to slide up and down, keeping the pressure of the
gas constant. (a) How much work is done on the gas
as the temperature of 0.105 mol of the gas is raised from 10.0°C to
260°C? J b) What does the sign of your answer to...
Determine the amount of work done on an ideal gas as it is heated in an enclosed thermally isolated cylinder topped with a freely moving piston. The cylinder contains of nmoles of the gas and the temperature is raised from T1 to T2. The piston has a mass m and a cross sectional area A. (Use any variable or symbol stated above along with the following as necessary: R.)
A piston has an external pressure of 5.00 atm. How much work has been done if the cylinder goes from a volume of 0.140 liters to 0.570 liters.
OTHERMOCHEMISTRY Understanding the definitions of heat and work Lauren 1 atm pressure A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) piston cylinder From previous experiments, this chemical reaction is known to...
