A piston in an engine compresses the gas into a smaller volume The pressure does what?
As the piston compresses the gas into a smaller volume, the pressure of the gas increases. This increased pressure helps to ignite the fuel-air mixture in the combustion chamber, leading to the generation of power in the engine.
What does lifting a piston on a cylinder of a gas show?
Lifting a piston on a cylinder of gas shows the relationship between volume and pressure of the gas. As the piston is lifted, the volume of the gas increases, which causes the pressure to decrease. This demonstrates Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when temperature is held constant.
What it the State of a gas when its volume increases and its pressure decreases?
When the volume of a gas increases and its pressure decreases, the state of the gas is expanding. This typically occurs when the gas is allowed to do work by pushing against a piston, which results in an increase in volume and a decrease in pressure.
What are 3 factors that affect gas behavior?
Temperature: As temperature increases, gas particles move faster, increasing pressure and volume. Pressure: Higher pressure compresses gas particles closer together, reducing volume. Volume: Gas expands to fill the container it's in, with volume increasing as the container size increases.
If you shrink a container containing gas what happens to the volume of the gas?
If you shrink the container containing gas, the volume of the gas decreases because the gas particles are forced into a smaller space. This increase in pressure due to the reduced volume is described by Boyle's Law.

What is the relationship between pressure and volume in a piston engine as shown in a PV diagram?
In a piston engine, the relationship between pressure and volume is inversely proportional, as shown in a PV diagram. This means that as the volume of the gas inside the engine decreases, the pressure increases, and vice versa.
What is clearance volume of engine?
The volume between the engine head and piston when the piston is in the head dead center piston R - is expressed in cubic inches
What is the volume of a piston engine cylinders?
Displacement
What does compression ratio mean in car motors?
In an internal combustion engine, there are cylinders that have pistons in them. When the piston is down you have an open cylinder that has a specific size of volume that it will hold. When the piston moves back up to as high as it can, it compresses all that space into the new space and that is the compression ratio.
What will happen to gas pressure when the volume is decreased?
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.

Is piston cylinder process is constant pressure process or constan volume process?
A piston cylinder process actually includes two processes. The gas inside the piston undergoes both the constant pressure process and the contant volume process.
What does an air compressor do and how does it work?
An air compressor is a machine that compresses air to increase its pressure. It works by drawing in air and then using a piston or other mechanism to compress it into a smaller volume, which increases its pressure. This pressurized air can then be used for various purposes, such as powering tools or inflating tires.
What is meant by cc of the engine?
iti s volume occupied by displacement of d piston cc is d volume occupied by displacement of d piston
What is the compression ratio for an engine?
It is the volume of the cylinder/combustion chamber/head gasket/piston volume(dish/dome) when the piston is at the bottom of the stroke divided by the volume when it is at the top of the stroke.
Why diesel engines called constant volume engines?
They aren't.Gasoline engines are (sort-of) constant volume engines while Diesel engines are (sort of) constant pressure engines.In a gas engine, the combustion process is so fast compared to the travel rate of the piston that it all happens in the same volume, before the piston has had much time to move away.In a Diesel engine combustion is so much slower that the piston will actually have time to move away while fuel is still being burnt.As the volume of the combustion chamber increases during burn as the piston moves away, the pressure will remain pretty much the same throughout the burn.
