because yellow flames dont burn effectively and leave carbon
so burning with yellow flames leaves soot on the glassware

Is steam a type of heat wave a type?
No, steam is water as a gas.
What will a thermometer show if placed next to a beaker containing an exothermic reaction?
The exothermic reaction within the beaker releases heat energy, resulting in an increase in temperature of the materials inside the beaker.Now about the dispersion of the heat energy.Conduction: The beaker molecules and air molecules in touch with the heated material inside the beaker heat up by conduction and will continue spreading this heat in all directions.Via Convection: The heated air above the reacting materials rises, thus dispersing the heat via convection.Radiation: Any and all heated materials disperse heat via radiation. This type of heat transfer requires no medium.How far and how much energy is transferred depends on different variable, including the amount of energy given off by the exothermic reaction as well as the materials in the beaker, and air density.As to the dispersed heat affecting a thermometer placed next to the beaker---There are so many variables not given in the question.Is the thermometer bulb measuring air temperature? if so, is the heat given off by the exothermic reaction enough to raise the air temperature surrounding the thermometer bulb? If so, then the answer is that the thermometer will report a higher temperature reading.
What type of heat transfer is needed to change water in to water vapor?
The water must be heated.
What type of flame would have for the combustion of amyl alcohol have?
Cool flame, yellow & orange
What are easy conduction demos?
One simple way to demonstrate conduction by putting one end of a spoon directly above a flame. Heat will soon spread to the fingers of the person holding the spoon. Next , test other type of metals with varying lengths on the flame and have the participants determine how long it takes for heat to travel on different metals.
What type of matter is in a beaker that has chloride crystals and water?
A pure substance
What type of flame is used for heating in Bunsen burner?
The yellow flame is considered a safe flame. If you are using the Bunsen to heat you would open the air vent so the flame turns blue, try heat on a yellow flame and it'll end up covered in soot.
How do you control the type of Bunsen flame?
Decide which flame to use. If the air hole on the Bunsen is open you will get a roaring flame a more gentle heat, close the air hole a Little flame will be quiet.
Why do hot beakers crack in cold wale?
im assuming you meant to type water... this happens because heat makes things expand, whilst cold makes things contract. by putting a hot beaker in cold water, you put too much strain on the beaker because it is changing size so fast
How can different types of flame influence the cooking?
The type of flame is directly proportionate to the temperature the food cooks at. If the flame is low, that would make a simmering heat. If the flame is high, it would make boiling, sauteing and searing.
What is the difference between a type of energy and an energy resource?
well, a type of energy is kinetic, sound or gravitational potential energy, whereas an energy RESOURCE is where energy is from, like heat from a flame, the heat is the type of energy and the flame is the resource. hope this helped! answered by Sarah x
Is water a type of heat sink?
Yes! Water is a heat sink.
What type of flame will make gas explode?
The type of flame is just a normal flame
Radiation is the type of heat roasts the marshmallows?
When roasting a marshmallow the transfer of heat from the flame to the marshmallow is radiation.Radiation is the transfer of heat through energy waves. It can actually be considered conduction as well if you place the marshmallow into the flame, since that is the direct transfer of heat.
What type of heat is boiling water?
convection
What is a narrow beaker called?
The majority of beakers are not narrow. However, there is one type of beaker called the Berzelius beaker that is known for its narrowness.
Is steam a type of heat wave a type?
No, steam is water as a gas.
