The ability to burn is a chemical property?
964339
True.   \nThe phrase "Chemical property" is context-dependent, but generally refers to a material's behaviour at ambient conditions (i.e. room temperature, atmospheric pressure, oxygen-bearing atmosphere). This property becomes apparent during a chemical reaction, and can only be observed by changing a substance's chemical identity.\n\nA usefully general term, it is used to encompass\n\n    * electronegativity\n    * ionization potential\n    * flammability\n    * preferred oxidation state(s)\n    * coordination number\n    * preferred types of bonds to form e.g., metallic, ionic, covalent

*\n      Elements of Combustion (Fire Triangle)\n    *\n      All required for a fire to occur.\n    *\n      Trend is to include “Chemical Reaction” as fourth element (Fire Tetrahedron).\nFire Properties & Chemistry\n\n    *\n      Solids do not burn. Gases burn.\n    *\n      Fuel must release gases/vapors – may require heating. (Ray Bradbury – Fahrenheit 451)\n    *\n      Fuel gases must mix /w Oxygen in proper proportion (Lean / Rich - Flammable Range).\n    *\n      Must be a source of ignition.\nFire Terms\n\n    *\n      Flash Point\n    *\n      Flammable Range (Lean/Rich)\n    *\n      LEL/UEL (LFL/UFL)\n    *\n      Ignition Temperature\n    *\n      Flammable vs. Combustible liquids\n    *\n      Bonding and Grounding\n\n\nNotes:\n1 - Flash Point – minimum temperature a fuel must be heated before it will ignite\n2 - Flammable Range (Lean/Rich) – when there is an appropriate fuel/air mixture for combustion I.e. not too lean (too little fuel), not too rich (too much fuel)\n3 - LEL/UEL (LFL/UFL) – Lower Explosive (Flammability) Limit / Upper Explosive (Flammability) Limit. These are the upper and lower limits of the Flammable Range.\n4 - Ignition Temperature – How hot the ignition source has to be – usually higher than the flash point.\n5 - Flammable vs. Combustible liquids – Flammable liquids have flash points less than 100F for OSHA rules, 140F for DOT rules, and 140F for EPA Hazardous Waste rules (EPA uses the term “ignitable” instead of “flammable”). Combustible liquids have flash points higher than those. Flammable liquids are at or above flash point at normal/ambient temperatures.\n6 - Bonding and Grounding – refers to procedures to dissipate static electricity during handling or transfer of flammable/combustible liquids. Bonding means to electrically bond 2 containers. Grounding means to electrically connecting them to ground.\nClasses of Fires\n\n\nNotes:\nClass A – most common fire. A burning house is a class A fire.\n\nClass B – at home would occur with household chemicals (paint, strippers, solvent cleaners, etc.) or fuels (gasoline, oils, etc.) or in the kitchen with grease.\nlass C – danger from live electricity. GET POWER TURNED OFF.\n\nClass D – many metals will burn magnesium, aluminum, metallic sodium, are examples. Metal burns easier if it is in powder form or chips. Putting water on a metal fire is very dangerous – it may explode.\nFire Extinguishant Materials\n\n    *\n      Water - class A only - cools /removes heat\n    *\n      Dry Chemical - class A, B, or C - interferes with chemical reaction\n    *\n      Carbon Dioxide - class A, B, or C (usually C) - removes Oxygen / smothers fire\n    *\n      Halon – (being phased out - ozone) class A, B, or C (usually C) - removes Oxygen / smothers fire\n    *\n      Metl-X - class D only - specialized dry chemical for metal fires\n    *\n      Foam – Class B, holds down vapors\n\n\nNotes:\nHalon – Is a chloro-fluorocarbon (CFC), concerns about ozone layer depletion.\n\nFoam – Usually used by professional fire fighters.

More intense vibratory movements from the molecules mean more thermal energy transfer to the matter which become in contact with it.  So you can burn your skin if the object you touch is really too hot!

Yes, it could be used, for two reasons.\n\nFire requires three components to occur,these are Fuel,Heat and Oxygen.\nRemoving any one of these will extinguish a fire.\nLiquid nitrogen would actually remove two, thus making it twice as effective!\n\nHope this helps.

briefly its b. flammability ..its a chemical property which defined as the ease with which a substance will ignite, causing fire or combustion. \n\nfor more information : \n\nA physical property is any aspect of an object or substance that can be measured or perceived without changing its identity. Physical properties can be intensive or extensive. An intensive property does not depend on the size or amount of matter in the object, while an extensive property does. In addition to extensiveness, properties can also be either isotropic if their values do not depend on the direction of observation or anisotropic otherwise. Physical properties are referred to as observables.\n\nOften, it is difficult to determine whether a given property is physical or not. Color, for example, can be "seen", however, what we perceive as color is really an interpretation of the reflective properties of a surface. In this sense, many ostensibly physical properties are termed as supervenient. A supervenient property is one which is actual (for depend on the reflective properties of a surface - it is not simply imagined), but is secondary to some underlying reality.\n\nThis is similar to the way in which objects are supervenient on atomic structure. A "cup" might have the physical properties of mass, shape, color, temperature etc, but these properties are supervenient on the underlying atomic structure, which may in turn be supervenient on an underlying quantum structure.\n\nIn the common sense, physical properties can be separated from nonphysical properties. Typically a nonphysical property is associated with a living being. Anger and love are not things which are part of the mechanics of the universe, but terms we use to discuss mental states.\n\nLiterally, the physical properties of an object are defined traditional in a Newtonian sense, the physical properties of an object are angle, angle velocity, area, capacitance, density, electric charge, electric current, electric field, electric potential, energy, force, frequency, length, location, magnetic field, magnetic flux, mass, power, pressure, resistance, temperature, velocity and volume.

everything can burn at a high enough temp\nthey melt before burning because of physical properties\nit is part of the solid-liquid-gas chain\n***get smarter, dude, it is possible, have you ever thrown water on a fire that was 50,000 degrees?

a physical property is something you can see or measure.  stuff like temperature, or color.

Yes it can be dangerous.\n\nIt is a very reactive element and can explode/combust when it comes into contact with water, air, flames, acid etc.\n\nIt is generally stored in oil where it is relatively safe, because it is protected from the things mentioned above.

A flame is a mixture of gases undergoing a chemical reaction that gives off enough heat to continue the reaction in the molecules that have not yet reacted.  We get the impression that solids (like wood) burn, but it's really mainly the gases coming off of them that burn.  That's why it's easier to start a hot piece of wood on fire than a cold piece of wood.  The initial piece has to be hot enough so that the flamable products escape from it in vapor form.

Fire is not matter. The combustible material is a 'solid' like  wood, but can be a 'liquid' like gasoline. The wood combusts, releasing 'gases' such as Carbon Monoxide and solids such as ash particulates. The "fire" is the energy released in the form of heat and light. That's my simple explanation.

Chemical properties are properties such as boiling point, freezing point, melting point, electronegativity, flammability, and so forth.  Physical properties are the ones the human senses can pick up with out having to change the chemical, such as taste, smell, sound.

Can't answer this one accurately with the limited information you gave. What is being burned? Under what conditions is it being burned?  When you're talking of by products as opposed to products, the composition of the combustible material enters the equation. If you are burning a pure hydrocarbon fuel such as methane the products  are water vapor and carbon dioxide. Depending upon the conditions under which it was burned you might also get carbon monoxide. If the combustible material contained sulfur, nitrogen or other elements you might get gases such as sulfur dioxide or nitrous oxide as well.

Hydrogen is highly flammable, burning at concentrations as low as 4% H2. When mixed with oxygen, hydrogen explodes upon ignition. A unique property of hydrogen is that its flame is nearly invisible in air. This makes it difficult to tell if a leak is burning, and carries the added risk that it is easy to walk into a hydrogen fire inadvertently.

no oxygen is required\nthe equation for burning is:\nCxHy + CO2 --> O2 + H2O\n\nthe product is oxygen.. meaning you don't need oxygen in the first place to burn\nand on the sun, there are already zillions of carbon and hydrogen compounds which can burn with it, and you're forgetting CO2 is different than just O2.
