What is the process of spinning to separate lighter from heavier substances called?
The process of spinning to separate lighter from heavier substances is called centrifugation. This technique uses the force of gravity to separate materials based on their density within a rotating container. The heavier components are pushed to the bottom while the lighter components rise to the top, allowing for easy separation.
Petrol is a compound containing carbon and hydrogen when it is burnt in an engine it reacts with oxygen what are some of the substances called?
When petrol is burnt in an engine, the reaction with oxygen produces carbon dioxide, water vapor, and small amounts of other pollutants like carbon monoxide and nitrogen oxides. These substances contribute to air pollution and greenhouse gas emissions.
Why is saliva heaviery that water?
Saliva contains additional compounds such as proteins, electrolytes, and enzymes that are not present in pure water. These extra components contribute to the heavier weight of saliva compared to water.
Is nitrogen heavier than oxygen?
it is heavier
What gas is produced when polyethylene is burnt?
When polyethylene is burnt carbon dioxide and water vapors are released.
Can you get back burnt substances to their original state?
No, you can't get back burnt substances to their original state as combustion is an irreversible reaction.
What becomes heavier after getting burnt?
Magnesium becomes heavier after it is burnt. This is because the magnesium has chemically bonded with oxygen to form magnesium oxide. The oxygen adds the extra weight.
Does magnesium get heavier when burnt?
Yes, because it reacts with the oxygen in the air to form a new compound.
Why is coal a mixture?

What are 2 reasons why density is a useful property identifying substances?
Some substances look alike and the density can help you determine which is which. It also helps to tell which is heavier than the other.
What is the name of the place where rubbish are burnt?
A place where rubbish is burnt is called an "incinerator." It is a facility designed to burn waste materials at high temperatures to reduce their volume and neutralize potentially harmful substances.
Is outer planets made of heavier material than a inner planet?
No because the inner planets are made of rocky and hard substances and the outer planets are made of gassy lighter substances.
What are advantages and disadvantages of winnowing?
Disadvantages of WinnowingWinnowing is defined as a method in which heavier components of the mixture are separated from the lighter substances with the help of wind but this process does not work for materials heavier than grains like stones
How is settling used in sewage treatment?
Human waste is heavier than water, so it sinks to the bottom. Then, the water is pumped through a pipe leaving the heavier substances behind, and the waste is disposed of.Hope this helps. :)
What is inside smoke?
Inside smoke is water vapour, products of the combustion which may contain carcinogenic substances, and unburnt or partly burnt particulates.
