What is a fire in physics?

Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. Oxygen, fuel and heat are needed for fire to occur. This is known as the fire triangle. Combustion is when fuel reacts with oxygen to release heat energy.

What is fire made up of?

Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire’s intensity will be different.

What is fire and how is it formed?

Fire is the result of applying enough heat to a fuel source, when you’ve got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.

What is the chemistry and physics of fire?

These elements are input heat, fuel, oxygen, proportioning, mixing, and ignition continuity. All of these elements are essential for both the initiation and continuation of the diffusion flame combustion process. The first three elements–input heat, fuel, and oxygen—are represented by the fire triangle.

What is fire science explain in detail?

Fire science is the study of all aspects of fire, from fire behavior to fire investigation. Many of those seeking to become a firefighter or obtain a career in fire prevention, protection, or safety might pursue a degree in fire science. Read on to find more information about fire science.

Is fire made of atoms?

“What fire really is, is a whole bunch of fragments of molecules that have way too much energy,” Finnegan said. “So they are emitting that energy in the form of heat and light. That’s what we actually see.” These items are typically made up of molecules that contain carbon and hydrogen atoms.

What is the science of fire?

combustion
A fire itself is the result of a chemical reaction known as combustion, where fuel and oxygen react with one another and atoms rearrange themselves irreversibly. For this to occur, fuel must reach its ignition temperature, and combustion will continue if there is enough fuel, heat and oxygen.

What is the chemical composition of fire?

Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. Fire emits heat and light. Fire comes from the reaction between oxygen in the atmosphere and a fuel, such as wood or gasoline. When the fuel comes into contact with oxygen and is heated to its ignition point, fire is made.

What is the physics of fire?

The Physics of Fire. It’s all part of the physics of how fires start and spread. “The physics of combustion determine when and where we have a fire. Basically, in order to have combustion you need fuel, something burnable; you need oxygen, which we’re surrounded by; and then you need a source of energy to kick start the combustion reaction.

Is fire a form of matter?

Answer Wiki. Fire is not a form of matter; it is a chemical reaction. Fire is not made of any actual materials, but instead it is the result of chemical reactions from heating certain materials while they are in contact with oxygen . At a certain point in the combustion reaction, called the ignition point, flames are produced.

What is fire and what causes fire?

Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced.
