What instrument would be suitable for holding for a liquid while heating it over a flame?
A beaker or flask is suitable for holding a liquid while heating it over a flame. It is made of heat-resistant glass and has a flat bottom to ensure even heating. It also typically has a handle for safe and easy handling.
3 differences between a heating flame and a safety flame?
A heating flame, typically a blue flame, is characterized by a more complete combustion, producing higher temperatures for efficient heating. In contrast, a safety flame, often yellow or orange, indicates incomplete combustion, resulting in lower temperatures and visible soot. Additionally, a heating flame is more stable and focused, while a safety flame can be more diffuse and less efficient for heating purposes. Safety flames are often used in laboratory settings to prevent accidents and ensure visibility of the flame's size and intensity.
Is heating liquid honey a change of state?
No. Simply heating honey, while making it less viscus, does not change its state. It remains a liquid. Unless heating is prolonged enough to cause evaporation, the honey will remain a liquid, so no change of state occurs by simply heating.
What is 4 differences between a yellow safety flam and a blue heat flame produced by a Bunsen burner?
The blue flame is really hotter than the yellow flame. If you put your hand over a blue flame and skim through it, it would burn you but if you put it over a yellow flame it wouldn't burn you that much.
What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.

Why is the test tube moved back and forth when heating liquids?
Moving the test tube back and forth while heating liquids promotes uniform heating and prevents localized overheating. This helps to ensure that the liquid heats up evenly and reduces the risk of boiling over or spattering.

Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
What are the names of the two Bunsen burner flames?
There are three: Safety flame: The hole is closed. Orange flame. Not too hot, Blue flame: Hole half open. Almost invisible. Hot. Used for heating liquids, Roaring blue flame: Hole open. Very hot blue part inside lighter coloured part. Used for heating solids.
Why don't wood melt on heating?
wood doesn't melt on heating because while heating the compound required to change that substance into liquid gets evaporated quickly when we start heating.
What is the difference between the label for a flammable liquid and the label for a flammable gas?
A label for a flammable liquid typically depicts a flame over a liquid, while a label for a flammable gas usually includes a flame or gas cylinder symbol. The label for a flammable liquid may also indicate the specific type of liquid, while the label for a flammable gas may specify the type of gas.
Why do you use the blue flame while using a Bunsen burner?
The blue flame of a Bunsen burner is the hottest part of the flame, making it ideal for heating and sterilizing purposes in a laboratory setting. The blue flame indicates complete combustion of the gas, leading to a cleaner and more efficient burn.
Consistent temperature can be achieved while heating a test tube by doing what?
Consistent temperature can be achieved by heating a test tube while moving the test tube all around the flame. Do not let only one part of the test tube rest on a flame but instead, keep moving the test tube slowly.
What are the two kinds of flames produced by Bunsen burner?
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
What is 4 differences between a yellow safety flam and a blue heat flame produced by a Bunsen burner?
The blue flame is really hotter than the yellow flame. If you put your hand over a blue flame and skim through it, it would burn you but if you put it over a yellow flame it wouldn't burn you that much.
