Which is more dense petrol or kerosene?
Petrol is more dense than kerosene. Density is a measure of mass per unit volume, and petrol is more dense because it has a higher mass per unit volume compared to kerosene.
What happens to the mass of an element when it burns?
When an element burns, its mass remains the same. The burning process involves a chemical reaction that rearranges the atoms of the element, but the total mass of the element before and after burning remains constant, according to the law of conservation of mass.
How will the mass of a pure substance be affected when the volume is increased?
The mass of a pure substance will remain constant even if the volume is increased. The mass of a substance is an intrinsic property that does not change with changes in volume.
When coal is burned is matter transformed increased decreased or destroyed?
When coal is burned, matter is not destroyed, but rather transformed. The coal is oxidized and undergoes chemical reactions to produce heat, carbon dioxide, and other byproducts. The total mass of the matter remains the same before and after burning.
Why has bitumen got a higher boiling point than petrol?
Bitumen has a higher boiling point than petrol because it is made up of larger, heavier hydrocarbon molecules with more carbon atoms. These larger molecules require more energy to break the intermolecular forces holding them together, resulting in a higher boiling point compared to the smaller hydrocarbons found in 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.
How do rides create the illusion of increased or decreased weight?
Rides create the illusion of increased or decreased weight by accelerating or decelerating the rider rapidly, which creates the sensation of either increased G-forces (making you feel heavier) or decreased G-forces (making you feel lighter). This sensation tricks your body into perceiving a change in weight even though your actual mass remains the same.
What type of relationship is displayed by decreased mass and decreased gravity?
Directly proportional
What happens to density if an objects volume remains constant but its volume is decreased?
If an object's volume remains constant but its mass is increased, its density will also increase. Density is defined as mass divided by volume, so if the volume stays the same while the mass increases, the density will increase as well.
What kind of relationship is displayed by decreased mass and decreased gravity?
The relationship between decreased mass and decreased gravity is inversely proportional. This means that as the mass of an object decreases, the force of gravity pulling on it also decreases. This is described by Newton's law of universal gravitation.
How can the mass of a coin be decreased?
You cant, the mass will always be the same, NO matter what.
What are the potential symptoms and health implications of low testosterone in females"?
Low testosterone in females can lead to symptoms such as fatigue, decreased libido, mood changes, and decreased muscle mass. Health implications may include osteoporosis, infertility, and an increased risk of cardiovascular disease.
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 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.
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 happens when density expands?
density is a measure of mass that is contained in a unit of volume for a particular substance. it increases it cannot expand if we say that density is increasing it means that either mass has increased or volume has decreased like on cooling volume decreases. on mixing(chemically or dissolving) mass increases.
