In a bunsen burner, the inner blue flame is hotter than the outer yellow flame because the blue flame is the primary combustion zone where complete combustion of the gas occurs. This results in a higher temperature due to the efficient burning of the gas. The outer yellow flame is cooler as it is the secondary combustion zone where some incomplete combustion occurs, leading to lower energy release and temperature.
What else can I help you with?
How hot is a green flame compared to other colored flames?
A green flame is typically not as hot as blue or white flames, but hotter than red or orange flames.
Can you measure the temperature of a flame of a Bunsen burner using a thermometer?
Yes, and No. You will get an inaccurate number since of air temperature and a few variables, but it will be relatively close. I do not recommend this, because a few things may happen, and even some I do not even know of. The thermometer will get hot and melt. Or explode. And many other things can happen.
What happens when you put a bimetallic strip in the flame of a burner?
When a bimetallic strip is exposed to the flame of a burner, the two metals in the strip expand at different rates due to their differing coefficients of thermal expansion. This causes the strip to bend as one side expands more than the other, demonstrating the principle behind the bimetallic strip's use in thermostats and temperature-regulating devices.
Does a flame have a shadow?
No, a flame does not have a shadow because it emits light and does not block light from other sources.
How do wicks work in candles and other flame-based products?
Wicks in candles and flame-based products work by absorbing the liquid wax and drawing it up to the flame. The heat from the flame vaporizes the liquid wax, which then burns and produces light and heat. The wick acts as a fuel delivery system, ensuring a steady and consistent burn.
Which flame is not suitable for heating in Bunsen burner and why?
The yellow flame is not suitable for heating in a Bunsen burner because it is a cooler, less efficient flame that produces soot and lacks complete combustion, resulting in lower heat output. The blue flame, on the other hand, is hotter, more efficient, and produces clean combustion, making it ideal for heating applications.
Why is safety flame on Bunsen burner not safe?
Because even though it is safer than other flames it is still a flame and it can burn you. It is so called the "safety flame" because it is visible (yellow) and so we have a visual reminder that the Bunsen burner is burning. Compared with the usual flame (blue) which is hard to see.
Why is the blue flame the hottest in science?
because you have the vents open on the bunsen burner the flame is getting more oxygen, making it hotter. Different flame types of Bunsen burner depending on flow through the throat holes (holes on the side of the Bunsen burner -- not to be confused with the needle valve for gas flow adjustment). 1) air hole closed (Safety flame used for when not in use or lighting). 2) air hole slightly open. 3) air hole half open. 4) air hole almost fully open (this is the roaring blue flame).
What is the difference between Bunsen burner and alcohol lamp?
Bunsen Burner: - Uses Gas - Achieves up to roaring blue flame - Used to melt solid objects Alcohol Lamp: - Uses Alcohol - Achieves Yellow flame only - Used to boil water
Why does a Bunsen burner have different temperatures on the flame?
The basic fuel to a Bunsen burner is a hydro carbon which on heating breaks the carbon bond with other elements with differentiated calorific value and combustion with oxygen. This results in different zones with differentiated temperature
What is the purpose of the burner?
The purpose of the burner is to provide a controlled flame or heat source for cooking, heating, or other processes. It converts fuel, such as gas or electricity, into heat energy for various applications.
What is the main difference of Bunsen burner to alcohol lamp?
The main difference between a Bunsen burner and an alcohol lamp is the type of fuel they use. A Bunsen burner typically uses natural gas or propane, while an alcohol lamp burns ethanol or other alcohol-based fuels. Bunsen burners provide a hotter flame and more control over the temperature compared to alcohol lamps.
Is green fire hotter then blue fire?
Assuming we're not throwing ions into the flame and the color is due strictly to temperature, the blue flame is hotter.The problem is that flames can be different colors for reasons other than temperature. Specifically, they may contain ionized materials with strong emission lines that color the flame. Probably the easiest example to observe using ordinary household materials is sodium which gives an orangish yellow color (easily seen by dropping a few crystals of table salt into the flame of a gas stove).The reason that hotter flames are blue is that blue light is more energetic than red light. A hotter flame has more energy, and therefore generates more energetic light.
Why the tempr of tip of flame is hotter than other zones?
The tip of a flame is hotter because it contains the highest concentration of combustible gases and is closest to the source of ignition. As the fuel is burned and rises upwards, it reaches its peak temperature at the tip before cooling down as it moves away from the flame.
What is a green flame on a Gas stove one burner does not come on automatically when you light it manually there is a brief green flame What is this?
A green flame on a gas stove can be caused by copper or other metal particles burning in the flame. This can happen if there is a build-up of dust or debris in the burner. It is usually safe to continue using the stove, but you may want to clean the burner to prevent this from happening.
Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light.

What does a wing tip do in the lab?
It can either spread a Bunsen burner flame or cause the other chemists to comment that you are over-dressed.
