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.
How does luminous flame exist?
A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.
What kind of flame would you use if you have to boil a solution?
For boiling a solution, a medium to high intensity flame is typically used to provide enough heat to raise the temperature of the solution to its boiling point. Adjust the flame intensity based on the size of the container and the volume of the solution being heated.
What is the colour of chloroform when heated?
Chloroform is a colorless liquid at room temperature. When heated, it may turn to a colorless gas.
When a substance is heated what is it called?
Thermal Decomposition

What happens to the density of objects when the get heated?
Raising the temperature the density is lowered.
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.
How do some objects change when they are heated?
Solid objects may melt into a liquid form when they are heated. Liquids may become gases when heated. When objects are combined and heated, they can become new objects altogether, like in cooking.
if two objects different in size were heated at a very high temperature which object would cool the fastest?
If two objects were heated quickly to the same temperature, one larger in size than the other, then they would cool at different temperatures. The smaller one would cool faster as it has less mass that is able to hold the higher temperature as long.
Does temperature affects the density?
Temprature affects the volume, since most objects expand when they are heated. And density is mass / volume.
How the temperature affects the density?

What objects give off light because of high temperature?
Objects such as stars, light bulbs, and burning candles give off light due to high temperature. When an object is heated to a high temperature, it emits electromagnetic radiation in the form of visible light.
Do most objects give off their own light?
No, most objects do not give off their own light. Objects either reflect light from a light source or emit light when they are heated to a high temperature.

This is different from a non-luminous flame, which does not produce visible light.
What objects can radiate energy?
Objects that can radiate energy include stars, light bulbs, heated coils, and the Earth's surface. The type of radiation (such as heat, light, or electromagnetic waves) emitted by an object depends on its temperature and composition.
