What happens if you use a luminous flame to boil water in a test tube?
Using a luminous flame to boil water in a test tube can lead to incomplete combustion, resulting in the formation of soot or carbon particles that may contaminate the water. It may also affect the purity of the water due to the combustion products in the flame. It is recommended to use a clean, blue flame for heating applications in the laboratory to avoid this issue.
The procedure indicates that the amount of time th test tube was kept in th boiling water bath should be minimized why was this necessary?
The procedure indicates that the amount of time the test tube was kept boiling in the water bath should be minimized. The water bath should never be allowed to boil dry.
What happens to the water in the small tube as the water in the test tube absorbs heat?
As the water in the test tube absorbs heat, its temperature increases, causing it to expand. This expansion can create a pressure difference that may cause the water in the small tube to either rise or flow, depending on the setup. If the small tube is connected to the test tube, the heated water may push some of the water in the small tube upward, demonstrating the effect of thermal expansion.
What happens when you blow over the mouth of a test tube which is half filled with water?
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.
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 will happen to the liquid in the test tube after heating?
In my idea,it will not boil!!thats all!!
How do you heat a test tube?
You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. To heat a test tube you simply use a Bunsen burner. Make sure you use pliers to hold it with though because it will get very hot. Also you can change the heat of the Bunsen burner by switching it to the blue flame. you always hold it away from you and your lab partner. heat it sideways and slowly run it through the flame to distribute the heat evenly.

How can a half test tube of sugar and a half test tube of water add up to one full test tube?
When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.
Alternate Wordings for 'Which freezes first cold water or hot water or salt water?
One alternate wording is At waters freezing temperaturethere are 3 test tubes, cold water is in test tube A, hot water is in test tube B, and salt water is in test tube C. Which test tube at (32 degrees) which will freeze the fastest? i hope i helped!
How high is 2 mL of water in a test tube?
It depends on what size test tube you are using.
What happens to the level of water in a test-tube as hydrogen is produced?
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...
