Why has bitumen got a higher boiling point than petrol?
because bitumen has higher molar mass than petrol (more molecules than petrol), bitumen needs more energy to vaporize its molecules than petrol
Can the mass of a coin be decreased by melting it?
No, if you melt a coin it is still the same mass just in a different form.
What happens to the mass of an element when it burns?
The weight of it increases
How will the mass of a pure substance be affected when the volume is increased?
Not at all.
How sugarcane juice can be converted into petrol?
sugarcane juice has molecular formula C12H22O11 ,petrol has a molecular formula C16H22.when we remove the oxygen by adding pd and by adding some amount of carbon we can able to get correct molecular formula of petrol
What happens to acceleration when mass is increased?
it gets decreased
Is volume mass and density changed by pressing a piece of styrofaom to halve its size?
The mass isn't changed. Since the volume is decreased, the quantity (mass/volume) is increased, meaning that the density is increased.
What item decrease when heat is applied density mass or volume?
Volume increased so density decreased
How does a change in mass affects the accelaration of an object?
Force = Mass * Acceleration (F = m * a)Therefore, if the mass of an object is increased, then the force required to accelerate to a given velocity will be greater. If the mass is decreased, then the force required to accelerate that object to a given velocity will become smaller.
What type of relationship is displayed by decreased mass and decreased gravity?
Directly proportional
If the temperature of a gas in a movable piston is decreased what will happen to the density of the gas?
It will increase. Density is mass/volume. Mass remains constant since no matter is entering or escaping. Lowering the temperature decreases the volume. Same mass in a smaller space= increased density.
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.
How can the mass of a coin be decreased?
You cant, the mass will always be the same, NO matter what.
How is mass movement related to angle of repose?
Movement of a material will occur if the angle of repose is increased by the addition of material, or if friction is decreased by oversaturation of the material, or in the event of a ground moving event.
What states that volume is neither created nor destroyed in chemical reaction?
As far as I know this is not true- volume can be increased or decreased. What is conserved in a chemical reaction is mass. Matter is not created or destroyed.
How is the angle of repose related to mass movement?
Movement of a material will occur if the angle of repose is increased by the addition of material, or if friction is decreased by oversaturation of the material, or in the event of a ground moving event.
Natural human growth hormone?
Human growth hormone (hGH) is a hormone that is naturally produced by the body. Effects of growth hormones are decreased body fat, increased muscle mass, increased bone density, increased energy levels, improved skin tone and texture, increased sexual function, and improved immune system function.
