What else can I help you with?
What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
yellow color in a luminous flame produces soot or carbon. carbon dioxide is present in the luminous flame but when its combined with oxygen the flame is nonluminous which is in a blue color. it takes a longer time because luminous flame is cooler than the nonluminous. I only know what luminous flame is. The inner part of luminous flame is blue while the outer part of the luminous flame is yellow. It is unsteady. Yeah. Carbon Dioxide is only present in the luminous flame. When oxygen is combined with the flame, the flame will become non- luminous which is inner and outer part are blue. Hmm. Actually luminous flame's hottest part is at the bottom while non- luminous flame hottest part is at the middle and the top. That's all i know. If i know more, i will update for you. Thank you!

WHICH two substance which expands on heaTing?
Two substances that expand when heated are water and mercury. Heating these substances causes their molecules to become more energized and move farther apart, leading to an increase in their volume.
What happens to the color of the flame if you spray charcoal in the non luminous flame?
Sprinkling charcoal powder into a non-luminous flame will not change the color of the flame. The flame color is determined by the elements present in the fuel being burned, not by adding additional substances like charcoal.
What two flames flickers non-luminous or luminous?
The two flames that flicker both non-luminous and luminous are a candle flame and a gas stove flame. When burning normally, these flames emit light due to combustion. However, if they are disturbed or lack sufficient oxygen, they can flicker and may become non-luminous.
How does one become a heating contractor?
You can become a heating contractor if you go to college and you can also go to a heating and plumbing school for training. The fastest way to become a heating contractor is to go to the heating and plumbing school and get certified with a license.
What conditions would a flame become luminous?
A flame becomes luminous when it reaches a high enough temperature to emit visible light. This usually occurs when the flame is fuel-rich and produces soot particles that glow as they burn. They can also become luminous in the presence of certain chemical compounds, such as salts, that emit colorful light when heated.
Name two objects which are non-luminous at room temperature but can be made luminous when heated?
-- the filament in an incandescent light bulb-- the coils in a bread toaster
Is a lava a luminous object?
Yes, typically lava glows red, orange, yellow, or white before it cools sufficiently to harden and become a black solid. So, while it is still hot enough to remain a viscous liquid, it gives off light, making it luminous.
What become liquefied by heating?
Substances that become liquefied by heating are typically solids that have a melting point below the heating temperature. Common examples include ice, which turns to water, and metals like iron, which melt at high temperatures. Additionally, certain materials like wax and chocolate also liquefy when heated. This process occurs as the heat energy causes the molecules to move more freely, transitioning from a solid to a liquid state.
How does heating sulfuric acid affect its properties and reactivity?
Heating sulfuric acid can change its properties and reactivity. The acid may become more concentrated and corrosive, making it more reactive with other substances. This can lead to increased risk of burns or other hazards when handling heated sulfuric acid.
What happened to the salt after heating?
Salt will just become hotter after heating, it will never melt.
What will happen to sugar after heating?
it will become caramel
