Why fluorine and chlorine act as decolorizing agent?
Why fluorine and chlorine act as decolourizing agents? Answer : They can oxidize dyes to colorless substances. Litmus and universal indicators can be decolorized. Chlorine is used in the bleaching powder which bleaches the substances due to oxidizing capabilities of chlorine.
Can water displacement find the volume of substances?
Water displacement can accurately find the volume of substances as it represents the same amount of space or volume. An object placed into the water will displace the same amount of water volume as its own volume.
Is iron nail soluble to water?
No, it is not soluble in water. To be soluble in water means that the object can dissolve in water. Examples of soluble substances include salt, sugar and so on, while insoluble substances include oil.
What is the meaning of oxidising substances?
oxidising substances are substances which gives oxygen or gains hydrogen

Does freezing an object cause an object to expand?
Water is one of the things that expands when it freezes, yes. But most other substances get somewhat smaller (contract) when they freeze.
What makes certain substances float and others sink?
Substances with a density (mass per unit volume) greaterthan a liquid will sink in the liquid; if the object has a lower density it will float.
Why hazard symbols are used?
Hazard symbols are designed to warn about dangerous substances, materials, locations or object.
