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 does a test tube of fresh water freeze quickly in iced salt water?
salt lowers the freezing point of the water
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
Which is smaller a beaker or a test tube?
It depends on the volume of the beaker and the test tube. Although throughout my scientific experience, beakers are larger than test tubes.
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
Are there any liquids which would change to gas if placed in a tube and put into a beaker of boiling water?
yes

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

Which are used for storing liquids and chemicals?
test tube, beaker??
Why should a thermometer not touch the sides of the test tube and should be placed in the middle?
If you place the thermometer so it touches the sides of the test tube, you are measuring the temperature of the test tube, not the substance in the test tube. So, in order to get an accurate reading of the substance, do not touch the sides of the test tube with the thermometer.
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
