What determines the pressure of the gas in the cylinder? How much of that force (per unit area) is due to the weight of the pistion?james brug said:Homework Statement
A vertical cylindrical tank contains 1.80 mol of an ideal gas under a pressure of 1.05 atm at 22.0[tex]^\circ[/tex] C. The round part of the tank has a radius of 10.0 cm , and the gas is supporting a piston that can move up and down in the cylinder without friction.
What is the mass of this piston?

The mass of a piston is important because it affects the engine's overall performance. A heavier piston may result in slower acceleration, while a lighter piston may result in faster acceleration but less power. It is important for engineers to carefully consider the mass of the piston when designing an engine.
The mass of a piston is typically measured in kilograms (kg) using a scale or balance. The piston is weighed without any other components attached to it, such as rings or connecting rods.
Yes, the mass of a piston can be changed by altering its design and material composition. For example, using lighter materials such as aluminum instead of steel can reduce the mass of a piston.
Yes, the mass of a piston can impact fuel efficiency. A heavier piston may require more fuel to move, resulting in lower fuel efficiency. On the other hand, a lighter piston may improve fuel efficiency by reducing the engine's overall weight.
The mass of a piston can have a small impact on engine noise. A lighter piston may result in slightly louder engine noise due to faster acceleration, while a heavier piston may produce less noise. However, other factors such as engine design and exhaust systems have a larger influence on engine noise.
