Does a test tube hold more liquid than a flask?
No it does not
What does the term swirl mean in a laboratory experiment?
Twisting your test tube, Erlenmeyer flask, Florence flask, or beaker to mix chemicals when a stirring rod is unavailable
What do you use for holding a flask a beaker or a test tube on a ring stand?
The flask and the beaker are held up by a ring support with a wire gauze. The test tube is held with a Burette clamp. Sometimes a triangle can be used for all three but it has to be small enough to hold the test tube and large enough so the others will not to tip over.
During the cooling of the naphthalene why the boiling tube must be placed in a conical flask?
ensure even cooling of the napthalene
What is a suction flask?
A suction flask is the glass bottle used to hold the liquid sucked from the throat of an aspirating patient. It is a bottle with a rubber stopper in the top. The stopper has two holes in it. Into each of these holes is placed a glass (or plastic) tube. There is a long tube that extends to, or almost to, the bottom of the flask (Jar or bottle). The other tube is short and extends only to the bottom of the rubber stopper. The short tube is connected to a vacuum source, which creates a low pressure inside the bottle. The longer tube is connected to a device that can be put into the mouth and throat of a patient. Any liquid in the mouth and throat is sucked into the jar. Because it is heavier than air the liquid will settle in the bottom of the suction flask. Because the tube connected to the vacuum source is at the top of the suction flask liquid will not be sucked in the suction source. Usually there is a filter and device between the suction flask and the vacuum source to prevent any extraneous liquid from entering the vacuum source. Suction flasks have been replaced, nowadays, with plastic containers.
What is the difference between a test tube and an Erlenmeyer flask?
Does a test tube hold more liquid than a flask?
No it does not
If a chemical reaction produces a gas how can that gas be captured in a test tube?
The flask should contain the reactants, and a bung should be put in the top of the flask. a tube should lead to a gas syringe.
Do air particles change size or shape when air is removed from a flask?
No.
How did the designs of Pasteur flask help him successfully refute the hypothesis of spontaneous generation?
It showed that microorganisms can only enter the flask as airborne particles.
How did the design of pasteurs flask help him successfully refute the hypothesis of spontaneous generation?
It showed that microorganisms can only enter the flask as airborne particles.
How did the design of pasteurs flask help him successfully refute the hypothesis of spontanous generation?
It showed that microorganisms can only enter the flask as airborne particles.
What kind of dish do you mix chemicals in?
Examples: Berzelius flask, Erlenmeyer flask, Petri dish, a mojar, a crucible, a test tube, etc.
Which of the following is the best instrument to use to prepare a solution beaker test tube crucible volumetric flask NextReset?
The volumetric flask is the best.
How can you separate mixture of sugar and liquid?
Heat till the liquid boils, if you just want the sugar. If you want both, perform simple distillation, you must put the sugar in a flask, put a flame under the flask, and attach a tube to the flask (must have an airtight fit). Then attach a liebig condenser to the tube, and a receiving tube to the end of the liebig condenser. Have a flask under the receiving tube to collect the liquid. What will happen, as you heat the mixture is: all the liquid will evaporate, go along the tubes, and condense at the liebig condenser back into liquid, and it will dribble into a flask. The sugar will be left in the original flask. Getting both of them is more complicated than getting just the sugar :)
What is another name for a test tube?
another name for test tube is culture tube or sample tube
How is heat transferred away from a vacuum flask?
a vacuum flask is not 100% vacuum. it contains some particles or gas molecules which absorbs a small amount of heat.
