What happens if you use a luminous flame to boil water in a test tube?
Using a luminous flame to boil water in a test tube can lead to incomplete combustion, resulting in the formation of soot or carbon particles that may contaminate the water. It may also affect the purity of the water due to the combustion products in the flame. It is recommended to use a clean, blue flame for heating applications in the laboratory to avoid this issue.
Why does the water boil in container when the utensil is placed on a flame?
due to conduction
What will happen to the water if you put a cup of water in a kettle and place it in the flame?
The water will warm until it reaches the same temperature as the flame. If the flame is hot enough, the water will eventually boil when it reaches 100ºC, and will then be converted to steam (water vapor).
When i boil water there is a blue residue left what is it?
Pure water has no residue; residues originate from impurities in water.
Why yellow flame boils water quicker than blue flame?
It depends upon what is coloring the water. It could boil faster or slower. If it is boiling faster, then it means that the dissolution of that substance in the water was endothermic. In other words, energy was taken into the solution when it dissolved. That extra energy puts the solution closer to boiling compared to plain water.
What kind of flame takes longer time to boil water using Bunsen burner?
A yellow flame would take longer to boil water using a Bunsen burner compared to a blue flame. This is because the yellow flame is cooler and provides less heat energy for boiling water.
What Bunsen burner flame do you use to boil water?
For boiling water, you would typically use a medium to high, blue, non-luminous flame on a Bunsen burner. Adjust the air hole to achieve the desired intensity of the flame.

Why does the water boil in container when the utensil is placed on a flame?

What time does it take to boil the water if you use luminous flame?
Depends mainly on the amount of water and the starting temperature and the measure of the flame.
What will happen to the water if you put a cup of water in a kettle and place it in the flame?
The water will warm until it reaches the same temperature as the flame. If the flame is hot enough, the water will eventually boil when it reaches 100ºC, and will then be converted to steam (water vapor).
Is it possible to boil water with a small torch light within one hour?
Yes but the flame would have to be hot enough to boil water which is 100ºC(212ºF).
How do you heat a test tube?
You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. To heat a test tube you simply use a Bunsen burner. Make sure you use pliers to hold it with though because it will get very hot. Also you can change the heat of the Bunsen burner by switching it to the blue flame. you always hold it away from you and your lab partner. heat it sideways and slowly run it through the flame to distribute the heat evenly.
How long does it take to boil 150ml of water on a Bunsen burner?
It typically takes around 2-3 minutes to boil 150ml of water on a Bunsen burner, depending on the intensity of the flame and the efficiency of the burner.
When i boil water there is a blue residue left what is it?
Pure water has no residue; residues originate from impurities in water.
How did people get water in the 1850s?
The same way we get it now - it is boiled, but during that period they had to boil it in pans or kettles over a named flame
