What are the 4 types of fire?
Classes of fireClass A – fires involving solid materials such as wood, paper or textiles.Class B – fires involving flammable liquids such as petrol, diesel or oils.Class C – fires involving gases.Class D – fires involving metals.Class E – fires involving live electrical apparatus.
What are 4 types of matter?
There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don’t move much.
What is the formula for fire?
The heat of the flame will keep remaining fuel at ignition temperature. The flame ignites gases being emitted, and the fire spreads. As long as there is enough fuel and oxygen, the fire keeps burning. Fuel + oxygen (from the air) = combustion products (mainly CO2 + H2O) + heat energy.
What is the fifth state of matter?
Bose–Einstein condensateIn condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter (also called the fifth state of matter) which is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero (-273.15 °C, -459.67 °F).
Is plasma hotter than fire?
Plasma is different: it’s gas with its atoms’ electrons stripped off and free to flow. … In other words, it requires temperatures far higher than fire to produce the “hard” ultraviolet light and the electrical effects seen in plasmas. Your flame can’t just be white hot or blue-hot, it must be UV-hot.
What are the 7 types of matter?
The classical states of matter are usually summarized as: solid, liquid, gas, and plasma.
What does Bose Einstein condensate look like?
It looks like a dense little lump in the bottom of the magnetic trap/bowl; kind of like a drop of water condensing out of damp air onto a cold bowl.
How does fire kill you?
Smoke and toxic gases kill more people than flames do. Fire uses up the oxygen you need and produces smoke and poisonous gases that kill. Breathing even small amounts of smoke and toxic gases can make you drowsy, disoriented and short of breath. … A fire’s heat alone can kill.
Is fire a solid liquid or gas?
The flames are obviously not solid, nor are they liquid. Mingling with the air, they’re more like a gas, but more visible–and more fleeting. And on a scientific level, fire differs from gas because gases can exist in the same state indefinitely while fires always burn out eventually.
Is Earth living or nonliving?
The planet Earth is a mixed living and nonliving system. It is the suprasystem of all supranational systems as well as the total ecological system, with all its living and nonliving components.
Why do shadows kiss?
Why do shadows “kiss”? When you move a shadow close to another there is a certain point at which another shadow forms between them. … Because of this, there is an area called the penumbra, where the shadowing object creates a partial shadow. When two penumbras meet, it makes the “kissing” darker shadow.
What state of matter is fire?
Fire doesn’t fall into gas, because it doesn’t expand in the same way gas does. Fire doesn’t fall into liquid, because it doesn’t have a fixed volume. Fire doesn’t fall into solid, because it doesn’t have a fixed shape. Thus, fire is currently considered a plasma.
How long does it take for fire smoke to kill you?
2 to 10 minutesDepending on the density and heat of the smoke, it may take 2 to 10 minutes to pass out or die. If there is more oxygen in the room, then you would have more time (but not much). Fire burns oxygen, so as a fire continues to be active, more oxygen gets removed from the room.
Is the sun a gas?
The Sun is our nearest star. It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. … As we heat up liquid, the liquid turns to gas.
Is it possible to have no shadow?
So an object that truly cast no shadow at all would have to be complete invisible. … You create a shadow on the ground because visible light cannot pass through you, for the most part. So an object without a shadow would be an object which is completely transparent to visible light.
Is fire a energy?
The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter. The heat produced is also energy, not matter.
Do burn victims feel pain?
All burn injuries are painful. First-degree or very superficial partial-thickness burns may damage only the outer layers of the skin (the epidermis) but they cause mild pain and discomfort, especially when something such as clothing rubs against the burned area.
What happens to the body in a fire?
Bodies during burning The heat of the fire will cause significant damage to the body. The fire will cause the soft tissues to contract, which causes the skin to tear and the fat and muscles to shrink. The internal organs will also shrink. The muscles contract due to burning and this causes the joints to flex.
Is fire a gas?
For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in the air and a fuel, such as wood or propane. … While there is a small amount of ionization going on in an ordinary fire, most of the matter in the flame is a gas.
Is fire a light or heat energy?
Answer : Fire is heat and light from rapid combination of oxygen and other materials. The flame, which gives the light, is composed of glowing particles of burning material and luminous gases.
How hot is plasma fire?
Naturally occurring plasmas can reach temperatures of up to 106eV (1eV ~ 11600K) , in industrial ap-plications maximum temperatures lie around 1eV .
Is Sun a living thing?
For young students things are ‘living’ if they move or grow; for example, the sun, wind, clouds and lightning are considered living because they change and move. Others think plants and certain animals are non-living.
Does Bose Einstein condensate exist?
An international team of researchers has successfully produced a Bose-Einstein condensate (BEC) in space for the first time. … A Bose-Einstein condensate is a state of matter occurring after gas atoms with very low density are chilled to very near absolute zero and bunch up to form an extremely dense quantum state.
Is gas a smoke?
Visible and invisible particles of combustion Visible particles emitted from a fire are referred to as smoke. Invisible particles are generally referred to as gas or fumes.
Does fire have a shadow?
Note that fire can have a shadow not because the incoming light beam scatters off the light in the flame. … Fires can have shadows because they contain hot air and soot, and not because they contain light.
What is the biggest living thing on earth?
More precisely, a specific honey fungus measuring 2.4 miles (3.8 km) across in the Blue Mountains in Oregon is thought to be the largest living organism on Earth. Several species of fungi belong to the Armillaria genus, which is popularly known as honey fungus.
What has no shadow?
The main reason why the flame has no shadow is because the flame itself is a source of light. A shadow is the surface area which is less bright than its surroundings because something is blocking light partially or fully from that area. Therefore, a shadow is nothing but a darker area with the absence of light.
Is fire plasma yes or no?
The bottom line is that a flame only becomes a plasma if it gets hot enough. Flames at lower temperatures do not contain enough ionization to become a plasma. On the other hand, a higher-temperature flame does indeed contain enough freed electrons and ions to act as a plasma.
Is an apple living or nonliving?
An example of a nonliving object is an apple or a dead leaf. A nonliving object may have some characteristics of living things but does not have all 5 of the characteristics. A car can move and use energy, which makes it seem alive, but a car cannot reproduce.
Is Fire considered a living thing?
The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells. All living organisms is made of cells. Although fire needs oxygen to burn, this does not mean it is living.
