Why do only some substance burn with flame?
Substances that burn with a flame typically contain volatile components that vaporize easily when heated. These vapors can then mix with oxygen in the air and undergo combustion. If a substance does not have volatile components or if the conditions are not right for combustion (e.g., lack of oxygen), it may not produce a visible flame when burned.
Why does isopropyl alcohol burn when it comes into contact with an open flame?
Isopropyl alcohol burns when it touches an open flame because it is a flammable substance that easily ignites when exposed to heat.
What is the scientific meaning for flammable?
The term flammable describes a substance which if ignited, will burn in air; burning is a highly exothermic reaction in which various substances combine with oxygen producing a visible plasma that is called flame or fire.
What is the ability of a substance to react in the presence of oxygen and burn when exposed to flame?
The ability of a substance to react in the presence of oxygen and burn when exposed to flame is known as flammability. It is a measure of how easily a material can ignite and sustain combustion in the presence of oxygen. Materials with high flammability are more likely to catch fire and burn rapidly.
What colour flame do you get when you burn lithium chloride?
When you burn lithium chloride, or any other lithium salt, you get a crimson flame, due to the positive lithium ions. The heat from burning the substance excites the outer electrons of the lithium ions to higher energy levels, when they drop back to the ground state, energy is released as light, and the wavelength of that light corresponding to that drop is crimson, hence we see a crimson flame.

If a substance does not have volatile components or if the conditions are not right for combustion (e.g., lack of oxygen), it may not produce a visible flame when burned.
Whether or not a substance will burn is called what?
The flammability of a substance refers to whether or not it will burn. It is a measure of how easily a material will ignite and sustain combustion in the presence of a flame or spark.
Which substance will burn in bunse to give a brick red non luminous flame?
NaCl will burn with a brick-red colour in a non-luminous Bunsen flame.
Why do some liquids burn while others do not?
The chimicals in some liquids burn others do not.
Why does isopropyl alcohol burn when it comes into contact with an open flame?
Isopropyl alcohol burns when it touches an open flame because it is a flammable substance that easily ignites when exposed to heat.
What does cinders mean?
# A burned or partly burned substance, such as coal, that is not reduced to ashes but is incapable of further combustion. # A partly charred substance that can burn further but without flame.
Is cloth combustible substance?
Yes. Combustible means capable of burning.
What does a flame need to burn?
For a flame to burn it needs fuel, oxygen, and heat.
What is the scientific meaning for flammable?
The term flammable describes a substance which if ignited, will burn in air; burning is a highly exothermic reaction in which various substances combine with oxygen producing a visible plasma that is called flame or fire.
Why do fires burn certain colors and not others?
This depends on many things,2 of them are the tempreature of which your particular fire is burning by. Another thing which effects the colour of a flame is when you burn certain chemicals in a fire to perform flame tests. For example when a flame test is performed on Strontium(Sr2+)a scarlet red flame can be observed.
How does fire go out if its covered by a jar?
Fire requires oxygen to burn. No oxygen = no flame. When you put a flame in a jar it lives off the oxygen inside the jar for a while. Once you put a lid on the jar, eventually the jar will run out of oxygen and the flame will burn out.
What is the ability of a substance to react in the presence of oxygen and burn when exposed to flame?
The ability of a substance to react in the presence of oxygen and burn when exposed to flame is known as flammability. It is a measure of how easily a material can ignite and sustain combustion in the presence of oxygen. Materials with high flammability are more likely to catch fire and burn rapidly.
