First point, the specific heat capacity for water seems higher than any other liquid. So gradual rise in temperature is possible.
Second one, in case the boiling temperature is higher than that of water, then boiling of liquid is avoided so any mishappening with higher temperature could be avoided.

What is the advantage of using evaporation by water bath over direct heating method?
The advantage of using evaporation by water bath over a direct heating method is when heating directly, for example, with a Bunsen flame - the substance in the boling tube may decompose upon such an accelerated heating because of variations in the intensity of the flame and then may be scorched, while a water bath provides a constant heating of the subsatnce by distributing heat to the boiling tube equally throughout, so that the substance cautiously gets heated until a fixed point (be it the melting point or boiling point) is reached.
Can you boil water in a test tube suspended in a pot of water?
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.
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.
Is it important to heat the test tube in a boiling water bath each time the Benedict's test for glucose is carried out?
Yes, reaction won't go at room temperature.
Where can you buy boiling tubes?
The boiling tube store

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.
Why water bath must be used while heating ethanol and acetone?
A water bath must be used while heating ethanol and acetone because the temperatures at which they can be heated might break the container they are heated in. Some metals are also heated this way.
Would heating the culture in a sealed small diameter tube that is totally immersed in a water bath produce more accurate results that the use of tubes that are partially submerged in a water bath?
Yes it would. This is because the whole tube would be in the water, making the measurements the same throughout.
How do you make a silver test tube?
1. You fill a test tube with Silver Nitrate. 2. You heat a water bath until it is boiling using a Bunsen burner. When it has boiled turn off the Bunsen. 3.Add three drops of glucose and five drops of ammonia. 4. Put the test tube in the water bath. 5. Wait for it to turn silver!

Yes, reaction won't go at room temperature.
Why is direct heating of liquid substances in a test tube over the flame prohibited?
Provided that you use the wider kind of tube known as a boiling tube, this is not so. Of course it is dangerous to heat liquids in a narrow tube, as this can cause rapid boiling and the shooting of the liquid out of the tube.
Why do we heat the tube in a water bath and not directly over a flame?

What is the difference between a boiling tube and test tube?
A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass
