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! :)

What effect did the addition of sugar to Beaker B and salt to Beaker C have on the freezing point of the water in these beakers?
The freezing point is lower for a saline solution.
Beaker X contains 50cm3 of marbles while Beaker Y contains 100cm3 of water. When all the water in Beaker Y is poured into Beaker X what is the volume of the water in Beaker X?
The volume of the water in Beaker X will be 100cm3, as you are not adding any more water to the equation (50X+100Y is not 150Y or X, but 50X+100Y) The total volume of matter in Beaker X will be 150cm3, and if the beaker is labelled, the volume measure will indicate 150cm3 due to the displacement of water. But as the answer to your question, the volume of water in Beaker X must be 100cm3 even though visual indicators will not show this due to the displacement of water by marbles
How do you prove that water vapour is present in the air by using only a beaker and several ice cubes?
When ice cubes are kept in beaker the water vapour in the air condenses on the outer walls of the beaker.this shows the presence of vapour in air.
What collects on the outside of the beaker if you place a 5 ml water and few ice cubes in the beaker?
when ice cubes place in the beaker, outside of the beaker have a formation of water drops. by. JD
Can water in a beaker be made to boil by placing in a bath of boiling water?
Yes, as the water in the beaker will finally get the same water temperature in the water bath.
What is the tool to measure volume using water displacement?
A beaker is used to measure volume using water displacement.
How would the water get into the beaker?
When you pored it into the beaker it would be there. It has to be added by some process. Using the faucet or another container with water in it would be the simplest manner.

The freezing point is lower for a saline solution.
What instrument using for determination of concentration of salt water?
Measure out any volume of water in a pre-weighed beaker (or container...sigh*). Then bake the beaker in a warm oven until all the water evaporates and the beaker is dry. Reweigh the beaker . Subtract the original weight of the empty beaker from the new weight. You now have the weight of the salt present in your original amount of water ! NOTE: If you are using ocean water this may be imprecise due to other contaminants remaining in the beaker. AKA you are not JUST weighing salt at the end.

How do you measure the volume of an irregular object?
Place it in a graduated cylinder (or any other metered container), completely submerge the object, and record the amount of water displaced. ---------------------------------------------------------------------------------------- Place an empty beaker onto a second larger catch pan. Be sure that your catch pan will hold water without leaking, and make sure it is large enough to catch ALL of the water that will spill out of the beaker. Fill a beaker until you can see the meniscus above the rim of the container. CAREFULLY lower your irregular object into the beaker with water allowing the beaker to over flow into the catch pan. Once you have your object submerged in the beaker, remove the beaker from the catch pan. Let the little bit of water adhered to the exterior of the beaker drip into the catch pan for a few seconds to make your measurement as accurate as possible. Using a graduated cylinder, measure the volume of water that has over flowed into your catch pan. The volume of this water will be very close to the volume of your irregular object.
How is water droplets formed in the inner most surface of the beaker?
when the hot water in the beaker touches the cool surface of the beaker,the water condenses into water droplets.
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
How would it affect your results if you used a beaker with residual water in it to measure out your standardized sodium Huydroxide NaOH solution?
Depends on how accurate your results need to be. If you're not using grade A or B glassware and its just a standard beaker then the effect of the residual water will be negligible compared to the calibration error of the beaker.

What are the five steps of the displacement method?
Using a beaker, fill it with water. (But not all the way) Then, place your object in the beaker. Subtract the location of the water at first with the location of the water after. Ex. Location of water at first: 12 mL Location of water after: 15 mL 15-12=3 The objects volume is 3 mL
