What is the difference between blaze and fire?
Basically, they are pretty much the same, but slightly different. A blaze is a small flame or rather what someone would call a weak fire. And fire... is fire.
What can a blue flame of a Bunsen burner do to you?
The blue flame of a Bunsen burner has a temperature between 500 0C and 700 0C.
What are Two kinds of flame?
the yellow/safety flame - thats the one that burns less the blue flame - burns THE ROARING FLAME - that one burns a lot and you can tell the difference from the blue flame because it makes a roaring sound
What type of a flame is best to use?
if you are talking about what flame to use on a Bunsen burner than the yellow flame is to make sure that everyone knows that there is a flame but the blue flame (less visible) is used as the hotter flame and the better one.
What is the difference between red and blue flame?
Difference is the excitation and ionization energy of atoms in the flame, likely fuel atoms, such as propane, and atmospheric atoms, such as oxygen, argon, hydrogen, nitrogen, etc. In the blue flame, the energy released by the atoms in the flame is more energetic. This is because blue light is of higher energy than red light. Blue light is lower wavelength, higher frequency, and higher energy than red light. The reverse is true in the red flame, the atoms are not releasing as much energy because red light is of lower energy. When an atom enters the flame, it absorbs energy thus exciting electrons to higher energy levels (higher than ground state). At this point, the excited atom can simply release this energy as visible or non visible light--and often relax by non-radiative means. Or the atom can lose an electron because the energy absorbed was so high and continue to excite other electrons to other levels and possibly remove a second or third electrons if the flame was energetic enough. In a flame, usually only first ionization and excitation occur. After these electrons are excited to whatever level, they have to release energy. Often, these atoms release this energy, if the energy level correlates, in the form of visible light. Other times, the light is released in non-visible portions of the electromagnetic spectrum. The light emitted from a flame is a measure of the energy available in the flame. With a given gas etc. distributions of atoms in excited states can be calculated, after spectra are collected, with the Boltzman equation and for ionization calculations one can use the Saha equation.
What is the flame spread rating for glass?
Glass does not burn or contribute to flame spread, so it typically does not have a flame spread rating.
What is flame spread rating of carpet?
The flame spread rating of carpet is typically measured on a scale of 0 to 200, with lower numbers indicating a slower rate of flame spread. Carpet with a lower flame spread rating is considered safer in the event of a fire.
How do you calculate a flame spread rating?
A flame spread rating is calculated by measuring the rate at which flames spread along the surface of a material under controlled conditions. The rating is determined by comparing the material's performance to that of red oak, which is given a flame spread rating of 100. Materials with lower ratings have slower flame spread rates, indicating better fire resistance.
What is flame spread 10?
Flame spread 10 is a rating associated with the surface burning characteristics of a material. It means that the material has a low flame spread index and is considered to have good fire-resistant properties. Materials with a flame spread 10 rating are slow to ignite and will not contribute significantly to the spread of fire.
Surface flame spread rating of not more than 150?
A surface flame spread rating of not more than 150 indicates that the material has a relatively low propensity for flame spread. This rating is determined through standardized testing procedures and indicates that the material is considered to have moderate fire resistance properties. It is important for materials used in buildings to have low flame spread ratings to reduce the potential for fire hazards.
What is flame spread 20?
Flame Spread 20 is a fire resistance rating given to materials that exhibit moderate flame spread. This means they have a moderate capacity to resist the spread of fire. A lower number indicates better fire resistance, while higher numbers indicate more rapid flame spread.
Is there a real difference between flame-retardant and inflammable bedding?
There is a real difference. A flame-retardant bedding has filler that is not flame resistant, but the outer later is flame resistant. As for inflammable bedding, both the filler and the outer layer are both flame resistant.
What is the difference between a blue flame and a yellow flame?
the blue flame is hoter than the yellow flame.http://en.wikipedia.org/wiki/Flame hope this gives u the right picture
What is class 1 flame spread?
The test method used to assess the effectiveness of flame retardant products is BS476, Part 7 1987 and is used to classify a material in terms of "Spread of Flame". Class 1 is a low surface spread of flame, the highest achievable with the test method and is a performance normally required for walls and ceilings. In high risk areas such as escape routes Class 0, limited combustibility, is required. To comply materials must have a Class 1 Surface Spread of Flame and a low fire propagation to BS 476 Part 6 1989. Intumescent coatings are used to prevent the penetration of fire through a structure for a specific period in accordance with BS 476 pARTS 20-23 1987. Such coatings are given classifications with specific periods of time achievements, such as "30 minutes".
What is the difference between a goldfish and the flame of a burning candle?
the goldfish is a living thing
What is the difference between fire retardant and flame retardant coveralls?
Flame retardant means the material will burn at a slow rate. However, flame resistant is defined as resisting flames and the power to withstand any type of flame.
