you don't have to!
The above answer is dangerous and incorrect:You turn off the burner before the water evaporates so the glass will not shatter and spray glass shards and dangerous chemicals all over the lab.You should because then it will be so hot around 90-100 degrees and it can burn you

What factors affect the rate at which Bunsen burner heats water in a beaker?
tempareture ,nature of the substance and the controller of the bunsen burner
When heating water in a beaker with a Bunsen burner what flame is required?
The flame that comes out of the Bunsen burner. it's blue/pale violet.
What gasses come from a Bunsen burner?
The Bunsen burner uses natural gas to burn. Methane, CH4. Below is the equation of Bunsen burner combustion. CH4 + 2O2 --> CO2 + 2H2O Methane burns combined with oxygen gas ( with ignition from a flame ) from the air and carbon dioxide and water are the products of this Bunsen burner reaction.
Why can you not use a Bunsen burner to heat a flammable liquid?
It is too volatile to heat up with a bunsen burner as it could overheat because you can not regulate the heat that the bunsen burner is set to, whereas with apparatus such as a thermostatic water bath you can set it to a specific temperature.
How long does it take to boil ml of water in a Bunsen burner?
8.30 minutes

What do you put on top of a Bunsen burner that evaporates water to leave salt?
You put a tripod then a gauze on top.Then on top of the guaze you put a beaker of salt water.That will then evaporate to leave salt.

How would you put out burning clothing near a Bunsen burner?
Water.

What happens when you put salt in water while a Bunsen burner is heating it up?
The water will evaporate
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.
How obtaining salt from the sea?
by boiling sea salt water on a stove or bunsen burner
How long does it take to boil 100 ml of water in a Bunsen burner?
8.30 minutes
How do you separate charcoal powder from mixture of copper oxide?
i did this in a lab using methods of solution, filtration and evaporation : add dilute sulphuric acid to the solid/solid mixture ..heat on a Bunsen burner till bubbles appear then filter the solution, collect the filtrate in an evaporating dish and heat on a Bunsen burner until most the water evaporates or half the filtrate has evaporated .....remove the dish from the burner and leave it on a flat undisturbed surface for 48hrs to allow crystallization.
