work = pressure x change in volume or w = P∆Vw = (8.00 atm)(0.610-0.170 L) = 8.00 * 0.440 = 3.52 atm-L
and 1 atm-L = 101.325 Joules, thus...
3.52 atm-L x 101.325 J/atm-L = 356.664 Joules = 357 Joules (3 significant figures)
Use the equation W = -Pext*(delta V)..just plug in the numbers.
Ms. Swamy is gonna get you. This academic misconduct and appropriate action will be taken.
I believe the answer to a chemical reaction taking place with 100 cm2 and a piston is pushed out through 12 cm against an external pressure of 658 torr, the value of w is 175.465 joules.
increases,the volume increases
The physical state of matter can also be changed by changing the pressure. In other words, the physical state of matter can also be changed by increasing pressure or decreasing pressure. For example, gases can be changed into liquids by increasing the pressure (accompanied by lowering of temperature). There is a lot of space between the particles of a gas. We can reduce the spaces between the particles by enclosing it in a cylinder and compressing it by pushing in the piston.
The pressure is higher than it was at first. A measurement cannot be given from these details.
A cylinder is a basic geometric three dimensional figure. The base is a circle. A cylinder can be described as an enclosed tube. It cannot be classified as a polygon since all of the sides are not segments.
A piston has an external pressure of 10.0 . How much work has been done if the cylinder goes from a volume of 0.170 liters to 0.460 liters.
In terms of engines, an external combustion engine such as a steam engine burns fuel outside of the pressure cylinder used to drive the piston. An internal combustion engine such as a petrol or diesel engine burns the fuel inside the pressure cylinder used to drive the piston.
Internal combustion engine is where the fuel is ignited in the cylinder to make the piston move, petrol or diesel. A steam engine has an external pressure vessel to supply the steam to the cylinder to push the piston. the is no combustion in the engine as such.
A piston cylinder process actually includes two processes. The gas inside the piston undergoes both the constant pressure process and the contant volume process.
Twice as much
gas pressure has to get round the back of the ring to force it against the cylinder wall
First you need to know what force is required. The pressure the cylinder is going to work at. From this you can wok out the area of the piston and then the diameter of the piston. Force = Pressure x Area
A 2.0 liter engine means that the total volume of all the cylinders is 2.0 liters, or a different way to put it, a 4 cylinder that is a 2.0 liter has 0.5 liters of volume from when the piston is at the top of the cylinder to when it's at the bottom of the cylinder.
Essentially, they are the same, pressurised gas in a closed cylinder forcing a piston along which turns a crank via a con rod converting linear to rotary force. The main difference is how the pressurised gas is delivered: In an internal combustion engine, fuel and air are sucked into the cylinder, valves are closed, fuel/Air is ignited, combustion takes place, heat makes pressure. So the pressure by combustion is created inside the cylinder (internally) In an external combustion engine, the gas is pressurised prior to entering the cylinder, in the case of a (piston) steam engine, water is boiled (by coal or other fuel combustion) in a closed container (boiler) to create pressurised steam, which is then delivered to the cylinder under pressure. So the pressure by combustion is created outside the cylinder (externally)
Decrease, 4
pressure in cylinder over piston area = force force over stroke = work
