How does cold water turn in to hot water?
Heat it. Place a 300ml sample of the cold water in a 500ml beaker and place the beaker on a retort stand about six inches above a standard laboratory Bunsen burner. Turn on the gas and ignite the Bunsen burner. Allow the flame to heat the water for several minutes. When small bubbles begin to form in the water, shut off the Bunsen burner and measure the temperature.
What does a gentle flame on a Bunsen burner do?
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
Why cant you heat something close to the barrel of a Bunsen burner?
Because that is just cold unburnt gas
When doing Bunsen burners which flame do you use the most?
The flame that you use the most is the safety flame. The safety flame is the yellow one it is not too hot and not too cold. The air hole should be half open for the safety flame and it makes a hissing sound. Your Welcome xx :D
When Bunsen burner is lit below a wire gauze the flame initially burns below the gauze after sometime the flame burns both below and above the gauze explain this observation?
At first, the air above the gauze is cold and heavy therefore, it cannot be ignite. After sometime, the hair above gets heated and becomes light hence can be ignited thus the flame burns above the gauze. Guys rate my answer please 😉💫
How do you know the expansivity of a bimetallic strip?
You can test the bimetallic strip's expansivity by placing it in a hot or cold environment, such as a refrigerator or a Bunsen burner. The strip that contracts or expands more has a higher expansivity than the other.

cold flame forms
What is the cold can a flame be?
A flame cannot be any cold but always hot even at the first instant it is lit.
Why doesn't cold water make a hot burner cold?
Heat is a form of energy and due to the principal of thermodynamic equilibrium, will constantly seek a state of equilibrium. The reason a hot burner does not become cold is because as the energy is transferred to the cold water more energy is being put into the burner through either electricity or gas. If there was no source of energy to the burner, then the cold water would cool down the hot burner, though the cold water would also heat up in the process, to the point where both are at room temperature.
What is a sub zero flame?
it is a cold flame that freezes anything it touches
