What do you mean by burns?
burn is an injury to the skin or other tissue, caused by heat, cold, electricity, chemicals, friction or UV radiation (such as sunburn). Most burns are caused by hot liquids (called scalding), solids, or the heat of fire. While the incidence is similar in men and women, the underlying causes are often different.
What is burning?
combustionor combustion, is a high temperature exothermic redox chemical reaction between a fuel (reducing agent) and an oxidant (usually atmospheric oxygen), producing oxidation products, usually gaseous, in a mixture called smoke.
What can make a fire?
Fire triangle. Three things need to be properly combined before ignition and combustion can occur –Heat, Oxygen and Fuel. Must have fuel to burn. There must be air to supply oxygen.
What are the 4 components of fire?
Oxygen, Heat and Fuel Often referred to as the « Triangle of Fire ». Add the fourth element, the chemical reaction, and you actually have a fire « tetrahedron. » The important thing to remember is this: take any of these four things away and you won’t catch fire and you won’t catch fire.

Which gas is needed for combustion?
oxygen Necessary for burning or burning to occur.
How would you describe fire?

Why does combustion require oxygen?
Oxygen supports the chemical processes that take place during a fire. When the fuel burns, It reacts with oxygen in the surrounding air, releasing heat and producing combustion products (gas, smoke, embers, etc.). This process is called oxidation.
What are the 3 types of burns?
There are three types of burns: first degree burn injury Only the outer skin. Second-degree burns can damage the outer layers and the layers below. Third-degree burns can damage or destroy the deepest layers of skin and tissue below.

Do fires need oxygen?
A fire needs only about 16% oxygen to burn. Without oxygen, fire will not burn. …to recap, in order for combustion (the chemical reaction of fire) to happen, you need three elements to work together. These elements are fuel, heat and oxygen.
Can it burn without oxygen?
Fire cannot burn without oxygen. …then the burning of stars is a nuclear reaction, not a chemical reaction like a fire on Earth (when a candle burns, the atoms themselves remain the same: only the molecules are affected).
How did the fire start?

Does fire burn in space?
Fires can’t start in space itself because there There is no oxygen in a vacuum — or anything else. However, within the confines of the spacecraft, unaffected by gravity, the flames behave in strange and beautiful ways. They burn in unfamiliar shapes at lower temperatures and are powered by unusual chemicals.
How can a fire start underwater?

Is the sun made of fire?
The sun is not « made of fire ». It is mainly composed of hydrogen and helium. Its heat and light come from nuclear fusion, a very different process that doesn’t require oxygen. Ordinary fire is a chemical reaction; fusion merges hydrogen nuclei into helium and produces more energy.
3 What is the fuel that burns?
It consists of three elements – fuel, heat and oxygen – All must be present to light the fire. It also demonstrates the interdependence of these components in creating and sustaining fires, and tells us that removing any of these components can prevent or extinguish fires.
