A fuel-air mixture is placed in a cylinder fitted with a piston. The original volume is 0.345-L. When the mixture is ignited, gases are produced and 885 J of energy is released. To what volume will the gases expand against a constant pressure of 635 mmHg, if all the energy released is converted to work to push the piston? I dont understand why you use Pascals and m^3? can you explain

1/2 Question 3 A piston-cylinder assembly fitted with a paddle wheel contains air, initially at 38°C, 125 kPa, and a volume of 0.02 mº. Energy in the amount of 1.8 kJ is transferred to the air by the paddle wheel. The volume of the air in the piston-cylinder increases to 0.05 mº at constant pressure. If the heat transfer between the air and its surroundings can be ignored, determine (a) the mass of the air in the piston-cylinder (b) the...

A cylinder if fitted with a floating piston oriented horizontally (the gas is the system and by having a floating piston it maintains constant pressure). It contains 26.0 L of argon at 30.0C and 1 bar pressure. The system is then heated to 300.0C. Argon can be considered a monatomic gas and therefore would have a Cv = 3R/2, where R is the ideal gas constant. Also for gases Cp = Cv +R. (pay attention to the units). If you...

Air in a cylinder is compressed to one-tenth of its original volume without change in temperature. What happens to its pressure? Imagine now that a valve is opened in order to restore the initial pressure value. What percentage of the molecules have escaped? Consider a 40,000 km steel pipe in the shape of a ring that fits snuggly all around the circumference of the Earth. We are heating now the ring so its temperature increased by 1 degree C. Now,...
