Tube A is placed in a beaker with iced water to cool down the contents of the tube quickly. This is useful for experiments where rapid cooling is needed, such as to stop a reaction or to preserve the sample. The cold temperature of the iced water helps to dissipate heat from the tube effectively.
What else can I help you with?
How can one lower a crystal in a beaker of water using a test tube?
Put a glass tube into the beaker of water so that it touches the bottom, then drop the crystal down the tube and put your finger over the top of the, then remove the tube gently, leaving the crystal behind in the beaker. After that laugh maniacally at the test tube and you might become an evil genius! Hope this helps! :)
Why is the leaf put in a test tube then in a beaker?
The leaf is placed in a test tube to collect any gases it releases, such as oxygen, during photosynthesis. The test tube is then submerged in a beaker, typically filled with water or another solution, to create a controlled environment that facilitates the observation of gas production. This setup allows for easy measurement of the leaf's photosynthetic activity by monitoring the volume of gas collected over time.
Why an empty test tube placed in water in a beaker with mouth outside the water surface shines like a mirror when seen at certain angle?
the test tube has air inside it.In the outer surface of the test tube is water.Due to the different media across the test tube surface the reflection of light occurs through the glass surface.Hence the test tube shines(behaves)like a mirror
Why does a test tube of fresh water freeze quickly in iced salt water?
The salt in the water lowers its freezing point, causing the water to become colder than 0 degrees Celsius. This rapid transfer of heat from the fresh water to the iced salt water speeds up the freezing process of the fresh water in the test tube.
Is starch more concentration in a tube or in a beaker?
The concentration of starch is the same regardless of whether it is in a tube or a beaker, assuming the same amount of starch is present in both. Concentration is typically expressed as the amount of solute (starch) per unit volume of solvent. It does not depend on the container in which the solute is placed.
Are there any liquids which would change to gas if placed in a tube and put into a beaker of boiling water?
yes

What is a large tube called?
the largest test tube is beaker
Removing pepper and sawdust from water?
distill it- boil it and have a tube that goes through cool water and into an empty beaker. look up distilling
How do you use the word beaker in a sentence?
the word beaker is a stupid word for a question
Which are used for storing liquids and chemicals?
test tube, beaker??
How would you separate the salt from the water and still have the water left?
Simple collect the water gas and cool it using a condenser in a condensing tube which will cause the water to return to liquid state and collect it in a beaker
How can you test a plant leaf for photosynthesis?
leave it in sunlight and water it, use a starch indicator to test presence of starch, or put an aquatic plant in a beaker of water and put a test tube upside down in the beaker surrounding the plant and leave it in sunlight and you should eventually see oxygen bubbles start to form up from the plant through the test tube
Why shouldn't a test tube be placed in the water bath when left to cool?
please!! i need it urgently
