The pressure is higher than it was at first. A measurement cannot be given from these details.

A piston in an engine compresses the gas into a smaller volume The pressure does what?
i am 99% sure it makes a small explosion big enough to push the piston up again and more gas gets in the spot and it does this again and again that's how a engine works.
If the temperature is kept constant and the piston moves down to decrease the volume the pressure increases because the gas particles?
The pressure increase because pV=k.
If you shrink a container containing gas what happens to the volume of the gas?
It compresses the gas and if it compresses too much, the container might not hold.
Im building a replica gasser with a 39 studebaker coupe . How do you build a 301 Chevy small block out of a 283?
Not sure if it applies to the engines you mentioned, but in most engines to change the size, it is usually just a matter of removing the engine block and having a machine shop re-bore the piston holes to a bigger size. You then put in the bigger diameter pistons, and also, the shape of the piston face may be machined or shaped differently to allow the larger air/fuel volume in the cylinder as it compresses the mixture on the upstroke for firing. For example, the Chrysler/Dodge 3.3 engine is the same engine as the 3.8, but the piston sleeves are bored out larger.
What is cubic capacity?
The cubic capacity is a measure of engine size. Cubic capacity is the total volume of the engine cylinders taken by piston movement (piston stroke). Apart from performance, it is one of the parameters of a combustion engine. it is the size of your engine block. for ex. a 305 has three hundred and five cubic all together.

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 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.
What is meant by the term clearance volume of an engine?
Clearance volume usually refers to the volume above the piston(to the top of the block) if the piston is receased( .30'' in the hole). + vavle relief in cc's+ the volume of the head gasket.
Why volume of gas decreases on increasing pressure on it at constant temperature?
It is possible to explain this mathematically in terms of the Ideal Gas Laws, however, it should also be intuitively obvious that this is what would happen; when you press on a flexible substance, it compresses. This is equivalent to asking, why is it that when you push on a spring, you can make it shorter. Force moves things. How do you put pressure on a gas? You put it in a cylinder (such as the cylinder in an internal combustion engine) with a movable piston, and then you push the piston downward. Obviously, squeezing the gas will decrease its volume in the cylinder. The point about the constant temperature is that if you do this but the gas heats up, then the gas is going to push back. Again, this is what we see in an internal combustion engine. You compress the gas, but then there is fuel burned inside the cylinder, the gas gets very hot, and the piston is forced upward with considerable strength. So the engine runs.
What is cubic capacity of engine in car?
It is the volume that the piston swipes in one stroke inside the engine cylinder.
