What is it called when the volume of a gas increases and the pressure decreases?
Charles' Law says that as pressure on a gas decreases, its volume increases. Charles' Law is an example of an inverse relationship.t It is not Charle's law It is Boyle's law Charles law states at constant volume, pressure is proportional to kelvin temperature And at constant pressure volume is proportional to kelvin temperature But Boyle's law states that at constant temperature pressure is inversely related to volume
What is constant volume?
The constant Volume process, also known as Isovolumetric, is where the volume is constant and does not change. In a P, V, Diagram this should be where volume is constant where Pressure is increased. The work done (area under the curve) would be = to 0 in this case.
What is the constant and the variables in Boyles law?
In Boyle's law, the constant is the temperature of the gas. The variables are the pressure and volume of the gas. Boyle's law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume.
What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?
the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
The density of petrol is 0.8gcm If the mass of petrol in a can is 4kg how many liters of petrol are there in the can?
The density of petrol is 0.8g cm3 which is the same as 800g per litre The mass of petrol supplied is 4Kg = 4000 grams =4000/0.8 = 5000cm3 5000cm3 = 5 litres of petrol. Answered by the longfield BTEC boys.
What is the difference between four stroke petrol engine and that of diesel engine?
Petrol engines are sometimes also called constant volume engines. They suck in a combustible mixture of fuel and air, compress it and then ignite it with a spark plug. Combustion is so fast that (most of it) takes place while the volume of the compression chamber(in the cylinder, between piston and cylinder head) stays the same. Then, as the piston moves away from Top Dead Center (TDC) combustion is (mostly) done and the pressure begins to drop. Diesel engines are also called constant pressure engines. They take in air, compress it to the point where the temperature alone will ignite the fuel, and then they inject the fuel. And fuel keeps being injected and burned as the piston moves away from TDC, keeping the pressure, kinda-sorta constant through the combustion phase.
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.
Differences between petrol and diesel engines?
sic difference between Petrol and Diesel engines that the difference of fuel and their mixture..in diesel we only compresses the Air and sprays Diesel but in Petrol Engines we compresses both the air and Petrol together and gets burnt with the the help of spark given by the Spark plug. I must add this, also the thermodynamic cycle is so different in diesel engines rather than petroleum engines. You can fined more in Reed's series volume 12
What is the clearance volume of petrol engine?
The volume occupied by the cylinder when the piston is at top dead centre is called clearence valume.
What is the volume of a petrol tank?
Petrol tanks are NOT a standard size.
How does the volume and pressure change in a tire after a long drive?
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
Why does a petrol pump have a volume measurer inside it?
A petrol or gas pump has a volume measurement device inside it to measure the expansion of the gases that come from the petrol. As the gases expand, they can actually cause explosions.
What is the the volume of a gallon of petrol?
1 gallon.
How may liquids described in term of shape and volume?
A solid has a constant volume and a determinate shape.A liquid has a constant volume but an indeterminate shape.A gas has an indeterminate volume and an indeterminate shape.liquids have a constant volume at a constant temperature, and take the shape of their container.

Why is petrol regarded as a better fuel than kerosene?
In petrol, the combustion of hydrocarbons present is complete and they burn with blue flame. However, in kerosene, the combustion is not complete. It burns with smoky flame accompanied by the release of unburnt carbon atoms. Therefore, petrol is regarded as a better fuel than kerosene.
Why Do Gasses Have Two Specific Heats?
One is for constant pressure, the other is for constant volume. These are not the same; for example, if the pressure is maintained constant, and the gas is heated, the volume changes.
