For slow heating with the maximum control, test tubes are heated in a water bath rather than in a flame. This can only heat the tube to the boiling point of water, 100°C or 212 °F.

What happens if you use a luminous flame to boil water in a test tube?
Carbon is settled on the test tube.
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.
How do you find the volume of water in a beaker?
7.6 ml
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
What is the standard test for CO2?
Get a test tube filled with lime water, then breathe into the test tube and if the lime water turns a milky white colour then there is carbon dioxide present!

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 high is 2 mL of water in a test tube?
It depends on what size test tube you are using.
Consistent temperature can be achieved while heating a test tube by doing what?
Consistent temperature can be achieved by heating a test tube while moving the test tube all around the flame. Do not let only one part of the test tube rest on a flame but instead, keep moving the test tube slowly.

What happens to iron placed in a test tube with a stopper?
Iron and oxygen in a test tube alone will not react (observed by placing a piece of iron in a test tube with a stopper).Iron and water in a test tube alone will not react (observed by completely submerging a piece of iron in water in a test tube with a stopper).Iron, water and oxygen in a test tube will react (observed by placing a piece of iron in a test tube and submerging half of it with water). The following reaction will take place: iron + water + oxygen ----> hydrated iron(III) oxide. Hydrated iron(III) oxide is the chemical name for rust, which will appear as orange flaking on the piece of iron. To speed up this reaction you can use a bit of salt as a catalyst.
